Heavens A, Sellentin E, Jaffe A, 2020, Extreme data compression while searching for new physics, Monthly Notices of the Royal Astronomical Society, Vol: 498, Pages: 3440-3451, ISSN: 0035-8711

Bringing a high-dimensional dataset into science-ready shape is a formidablechallenge that often necessitates data compression. Compression has accordinglybecome a key consideration for contemporary cosmology, affecting public datareleases, and reanalyses searching for new physics. However, data compressionoptimized for a particular model can suppress signs of new physics, or evenremove them altogether. We therefore provide a solution for exploring newphysics \emph{during} data compression. In particular, we store additionalagnostic compressed data points, selected to enable precise constraints ofnon-standard physics at a later date. Our procedure is based on the maximalcompression of the MOPED algorithm, which optimally filters the data withrespect to a baseline model. We select additional filters, based on ageneralised principal component analysis, which are carefully constructed toscout for new physics at high precision and speed. We refer to the augmentedset of filters as MOPED-PC. They enable an analytic computation of Bayesianevidences that may indicate the presence of new physics, and fast analyticestimates of best-fitting parameters when adopting a specific non-standardtheory, without further expensive MCMC analysis. As there may be large numbersof non-standard theories, the speed of the method becomes essential. Should nonew physics be found, then our approach preserves the precision of the standardparameters. As a result, we achieve very rapid and maximally preciseconstraints of standard and non-standard physics, with a technique that scaleswell to large dimensional datasets.

VII. Isotropy and statistics of the CMB, Astronomy and Astrophysics: a European journal, Vol: 641, Pages: 1-61, ISSN: 0004-6361

Analysis of the Planck 2018 data set indicates that the statisticalproperties of the cosmic microwave background (CMB) temperature anisotropiesare in excellent agreement with previous studies using the 2013 and 2015 datareleases. In particular, they are consistent with the Gaussian predictions ofthe $\Lambda$CDM cosmological model, yet also confirm the presence of severalso-called "anomalies" on large angular scales. The novelty of the currentstudy, however, lies in being a first attempt at a comprehensive analysis ofthe statistics of the polarization signal over all angular scales, using eithermaps of the Stokes parameters, $Q$ and $U$, or the $E$-mode signal derived fromthese using a new methodology (which we describe in an appendix). Althoughremarkable progress has been made in reducing the systematic effects thatcontaminated the 2015 polarization maps on large angular scales, it is stillthe case that residual systematics (and our ability to simulate them) can limitsome tests of non-Gaussianity and isotropy. However, a detailed set of nulltests applied to the maps indicates that these issues do not dominate theanalysis on intermediate and large angular scales (i.e., $\ell \lesssim 400$).In this regime, no unambiguous detections of cosmological non-Gaussianity, orof anomalies corresponding to those seen in temperature, are claimed. Notably,the stacking of CMB polarization signals centred on the positions oftemperature hot and cold spots exhibits excellent agreement with the$\Lambda$CDM cosmological model, and also gives a clear indication of howPlanck provides state-of-the-art measurements of CMB temperature andpolarization on degree scales.

V. CMB power spectra and likelihoods, Astronomy and Astrophysics: a European journal, Vol: 641, ISSN: 0004-6361

This paper describes the 2018 Planck CMB likelihoods, following a hybridapproach similar to the 2015 one, with different approximations at low and highmultipoles, and implementing several methodological and analysis refinements.With more realistic simulations, and better correction and modelling ofsystematics, we can now make full use of the High Frequency Instrumentpolarization data. The low-multipole 100x143 GHz EE cross-spectrum constrainsthe reionization optical-depth parameter $\tau$ to better than 15% (incombination with with the other low- and high-$\ell$ likelihoods). We alsoupdate the 2015 baseline low-$\ell$ joint TEB likelihood based on the LowFrequency Instrument data, which provides a weaker $\tau$ constraint. At highmultipoles, a better model of the temperature-to-polarization leakage andcorrections for the effective calibrations of the polarization channels(polarization efficiency or PE) allow us to fully use the polarization spectra,improving the constraints on the $\Lambda$CDM parameters by 20 to 30% comparedto TT-only constraints. Tests on the modelling of the polarization demonstrategood consistency, with some residual modelling uncertainties, the accuracy ofthe PE modelling being the main limitation. Using our various tests,simulations, and comparison between different high-$\ell$ implementations, weestimate the consistency of the results to be better than the 0.5$\sigma$level. Minor curiosities already present before (differences between $\ell$<800and $\ell$>800 parameters or the preference for more smoothing of the $C_\ell$peaks) are shown to be driven by the TT power spectrum and are notsignificantly modified by the inclusion of polarization. Overall, the legacyPlanck CMB likelihoods provide a robust tool for constraining the cosmologicalmodel and represent a reference for future CMB observations. (Abridged)

LVI. Detection of the CMB dipole through modulation of the thermal Sunyaev-Zeldovich effect: Eppur si muove II, Publisher: arXiv

The largest temperature anisotropy in the cosmic microwave background (CMB)is the dipole, which has been measured with increasing accuracy for more thanthree decades, particularly with the Planck satellite. The simplestinterpretation of the dipole is that it is due to our motion with respect tothe rest frame of the CMB. Since current CMB experiments infer temperatureanisotropies from angular intensity variations, the dipole modulates thetemperature anisotropies with the same frequency dependence as the thermalSunyaev-Zeldovich (tSZ) effect. We present the first, and significant,detection of this signal in the tSZ maps and find that it is consistent withdirect measurements of the CMB dipole, as expected. The signal contributespower in the tSZ maps, which is modulated in a quadrupolar pattern, and weestimate its contribution to the tSZ bispectrum, noting that it contributesnegligible noise to the bispectrum at relevant scales.

Mootoovaloo A, Heavens AF, Jaffe AH, Leclercq Fet al., 2020, Parameter Inference for Weak Lensing using Gaussian Processes and MOPED, Monthly Notices of the Royal Astronomical Society, Vol: 497, Pages: 2213-2226, ISSN: 0035-8711

In this paper, we propose a Gaussian Process (GP) emulator for the calculation both of tomographic weak lensing band powers, and of coefficients of summary data massively compressed with the MOPED algorithm. In the former case cosmological parameter inference is accelerated by a factor of ∼10–30 compared with Boltzmann solver class applied to KiDS-450 weak lensing data. Much larger gains of order 103 will come with future data, and MOPED with GPs will be fast enough to permit the Limber approximation to be dropped, with acceleration in this case of ∼105. A potential advantage of GPs is that an error on the emulated function can be computed and this uncertainty incorporated into the likelihood. However, it is known that the GP error can be unreliable when applied to deterministic functions, and we find, using the Kullback–Leibler divergence between the emulator and class likelihoods, and from the uncertainties on the parameters, that agreement is better when the GP uncertainty is not used. In future, weak lensing surveys such as Euclid, and the Legacy Survey of Space and Time, will have up to ∼104 summary statistics, and inference will be correspondingly more challenging. However, since the speed of MOPED is determined not the number of summary data, but by the number of parameters, MOPED analysis scales almost perfectly, provided that a fast way to compute the theoretical MOPED coefficients is available. The GP provides such a fast mechanism.

We present cosmological parameter results from the final full-mission Planck measurements of the cosmic microwave background (CMB) anisotropies, combining information from the temperature and polarization maps and the lensing reconstruction. Compared to the 2015 results, improved measurements of large-scale polarization allow the reionization optical depth to be measured with higher precision, leading to significant gains in the precision of other correlated parameters. Improved modelling of the small-scale polarization leads to more robust constraints on many parameters, with residual modelling uncertainties estimated to affect them only at the 0.5σ level. We find good consistency with the standard spatially-flat 6-parameter ΛCDM cosmology having a power-law spectrum of adiabatic scalar perturbations (denoted “base ΛCDM” in this paper), from polarization, temperature, and lensing, separately and in combination. A combined analysis gives dark matter density Ωch2 = 0.120 ± 0.001, baryon density Ωbh2 = 0.0224 ± 0.0001, scalar spectral index ns = 0.965 ± 0.004, and optical depth τ = 0.054 ± 0.007 (in this abstract we quote 68% confidence regions on measured parameters and 95% on upper limits). The angular acoustic scale is measured to 0.03% precision, with 100θ* = 1.0411 ± 0.0003. These results are only weakly dependent on the cosmological model and remain stable, with somewhat increased errors, in many commonly considered extensions. Assuming the base-ΛCDM cosmology, the inferred (model-dependent) late-Universe parameters are: Hubble constant H0 = (67.4 ± 0.5)  km s−1 Mpc−1; matter density parameter Ωm = 0.315 ± 0.007; and matter fluctuation amplitude σ8 = 0.811 ± 0.006.

LVII. Joint Planck LFI and HFI data processing, Publisher: arXiv

We present the NPIPE processing pipeline, which produces calibrated frequencymaps in temperature and polarization from data from the Planck Low FrequencyInstrument (LFI) and High Frequency Instrument (HFI) using high-performancecomputers. NPIPE represents a natural evolution of previous Planck analysisefforts, and combines some of the most powerful features of the separate LFIand HFI analysis pipelines. The net effect of the improvements is lower levelsof noise and systematics in both frequency and component maps at essentiallyall angular scales, as well as notably improved internal consistency betweenthe various frequency channels. Based on the NPIPE maps, we present the firstestimate of the Solar dipole determined through component separation across allnine Planck frequencies. The amplitude is ($3366.6 \pm 2.7$)$\mu$K, consistentwith, albeit slightly higher than, earlier estimates. From the large-scalepolarization data, we derive an updated estimate of the optical depth ofreionization of $\tau = 0.051 \pm 0.006$, which appears robust with respect todata and sky cuts. There are 600 complete signal, noise and systematicssimulations of the full-frequency and detector-set maps. As a Planck first,these simulations include full time-domain processing of the beam-convolved CMBanisotropies. The release of NPIPE maps and simulations is accompanied with acomplete suite of raw and processed time-ordered data and the software,scripts, auxiliary data, and parameter files needed to improve further on theanalysis and to run matching simulations.

Context. Existing cosmological simulation methods lack a high degree of parallelism due to the long-range nature of the gravitational force, which limits the size of simulations that can be run at high resolution.Aims. To solve this problem, we propose a new, perfectly parallel approach to simulate cosmic structure formation, which is based on the spatial COmoving Lagrangian Acceleration (sCOLA) framework.Methods. Building upon a hybrid analytical and numerical description of particles’ trajectories, our algorithm allows for an efficient tiling of a cosmological volume, where the dynamics within each tile is computed independently. As a consequence, the degree of parallelism is equal to the number of tiles. We optimised the accuracy of sCOLA through the use of a buffer region around tiles and of appropriate Dirichlet boundary conditions around sCOLA boxes.Results. As a result, we show that cosmological simulations at the degree of accuracy required for the analysis of the next generation of surveys can be run in drastically reduced wall-clock times and with very low memory requirements.Conclusions. The perfect scalability of our algorithm unlocks profoundly new possibilities for computing larger cosmological simulations at high resolution, taking advantage of a variety of hardware architectures.

We report a measurement of the E-mode polarization power spectrum of thecosmic microwave background (CMB) using 150 GHz data taken from July 2014 toDecember 2016 with the POLARBEAR experiment. We reach an effective polarizationmap noise level of $32\,\mu\mathrm{K}$-$\mathrm{arcmin}$ across an observationarea of 670 square degrees. We measure the EE power spectrum over the angularmultipole range $500 \leq \ell <3000$, tracing the third to seventh acousticpeaks with high sensitivity. The statistical uncertainty on E-mode bandpowersis $\sim 2.3 \mu {\rm K}^2$ at $\ell \sim 1000$ with a systematic uncertaintyof 0.5$\mu {\rm K}^2$. The data are consistent with the standard $\Lambda$CDMcosmological model with a probability-to-exceed of 0.38. We combine recent CMBE-mode measurements and make inferences about cosmological parameters in$\Lambda$CDM as well as in extensions to $\Lambda$CDM. Adding the ground-basedCMB polarization measurements to the Planck dataset reduces the uncertainty onthe Hubble constant by a factor of 1.2 to $H_0 = 67.20 \pm 0.57 {\rm km\,s^{-1}\,Mpc^{-1}}$. When allowing the number of relativistic species ($N_{eff}$) tovary, we find $N_{eff} = 2.94 \pm 0.16$, which is in good agreement with thestandard value of 3.046. Instead allowing the primordial helium abundance($Y_{He}$) to vary, the data favor $Y_{He} = 0.248 \pm 0.012$. This is veryclose to the expectation of 0.2467 from Big Bang Nucleosynthesis. When varyingboth $Y_{He}$ and $N_{eff}$, we find $N_{eff} = 2.70 \pm 0.26$ and $Y_{He} =0.262 \pm 0.015$.

Hotinli SC, Kamionkowski M, Jaffe AH, 2019, The search for statistical anisotropy in the gravitational-wave background with pulsar timing arrays, The Open Journal of Astrophysics, Vol: 2, Pages: 1-11

Pulsar-timing arrays (PTAs) are seeking gravitational waves from supermassive-black-hole binaries, and there are prospects to complement these searches with stellar-astrometry measurements. Theorists still disagree, however, as to whether the local gravitational-wave background will be statistically isotropic, as arises if it is the summed contributions from many SMBH binaries, or whether it exhibits the type of statistical anisotropy that arises if the local background is dominated by a handful (or even one) bright source. Here we derive, using bipolar spherical harmonics, the optimal PTA estimators for statistical anisotropy in the GW background and simple estimates of the detectability of this anisotropy. We provide results on the smallest detectable amplitude of a dipole anisotropy (and several other low-order multipole moments) and also the smallest detectable amplitude of a "beam’’ of gravitational waves. Results are presented as a function of the signal-to-noise with which the GW signal is detected and as a function of the number of pulsars (assuming uniform distribution on the sky and equal sensitivity per pulsar). We provide results first for measurements with a single time-domain window function and then show how the results are augmented with the inclusion of time-domain information. The approach here is intended to be conceptually straightforward and to complement the results of more detailed (but correspondingly less intuitive) modeling of the actual measurements.

Gravitational potentials that change in time induce fluctuations in the observed cosmic microwave background (CMB) temperature. Cosmological structure moving transverse to our line of sight provides a specific example known as the moving lens effect. Here, we explore how the observed CMB temperature fluctuations, combined with the observed matter overdensity, can be used to infer the transverse velocity of cosmological structures on large scales. We show that near-future CMB surveys and galaxy surveys will have the statistical power to make a first detection of the moving lens effect, and we discuss applications for the reconstructed transverse velocity.

The SO experiment in its currently funded form ('SO-Nominal') consists ofthree 0.4 m Small Aperture Telescopes (SATs) and one 6 m Large ApertureTelescope (LAT). Optimized for minimizing systematic errors in polarizationmeasurements at large angular scales, the SATs will perform a deep,degree-scale survey of 10% of the sky to search for the signature of primordialgravitational waves. The LAT will survey 40% of the sky with arc-minuteresolution. These observations will measure (or limit) the sum of neutrinomasses, search for light relics, measure the early behavior of Dark Energy, andrefine our understanding of the intergalactic medium, clusters and the role offeedback in galaxy formation. With up to ten times the sensitivity and five times the angular resolution ofthe Planck satellite, and roughly an order of magnitude increase in mappingspeed over currently operating ("Stage 3") experiments, SO will measure the CMBtemperature and polarization fluctuations to exquisite precision in sixfrequency bands from 27 to 280 GHz. SO will rapidly advance CMB science whileinforming the design of future observatories such as CMB-S4.

The direct detection of gravitational waves has provided new opportunities for studying the Universe, but also new challenges, such as the detection and characterization of stochastic gravitational-wave backgrounds at different gravitational-wave frequencies. In this paper, we examine two different methods for their description, one based on the amplitude of a gravitational-wave signal and one on its Stokes parameters. We find that the Stokes parameters are able to describe anisotropic and correlated backgrounds, whereas the usual power spectra of the amplitudes cannot – i.e. the Stokes spectra are sensitive to properties such as the spatial distribution of the gravitational-wave sources in a realistic backgrounds.

IX. Constraints on primordial non-Gaussianity, Publisher: arXiv

We analyse the Planck full-mission cosmic microwave background (CMB)temperature and E-mode polarization maps to obtain constraints on primordialnon-Gaussianity (NG). We compare estimates obtained from separabletemplate-fitting, binned, and modal bispectrum estimators, finding consistentvalues for the local, equilateral, and orthogonal bispectrum amplitudes. Ourcombined temperature and polarization analysis produces the following results:f_NL^local = -0.9 +\- 5.1; f_NL^equil = -26 +\- 47; and f_NL^ortho = - 38 +\-24 (68%CL, statistical). These results include the low-multipole (4 <= l < 40)polarization data, not included in our previous analysis, pass an extensivebattery of tests, and are stable with respect to our 2015 measurements.Polarization bispectra display a significant improvement in robustness; theycan now be used independently to set NG constraints. We consider a large numberof additional cases, e.g. scale-dependent feature and resonance bispectra,isocurvature primordial NG, and parity-breaking models, where we also placetight constraints but do not detect any signal. The non-primordial lensingbispectrum is detected with an improved significance compared to 2015,excluding the null hypothesis at 3.5 sigma. We present model-independentreconstructions and analyses of the CMB bispectrum. Our final constraint on thelocal trispectrum shape is g_NLl^local = (-5.8 +\-6.5) x 10^4 (68%CL,statistical), while constraints for other trispectra are also determined. Weconstrain the parameter space of different early-Universe scenarios, includinggeneral single-field models of inflation, multi-field and axion fieldparity-breaking models. Our results provide a high-precision test forstructure-formation scenarios, in complete agreement with the basic picture ofthe LambdaCDM cosmology regarding the statistics of the initial conditions(abridged).

We discuss a systematic effect associated with measuring polarization with acontinuously rotating half-wave plate. The effect was identified with the datafrom the E and B Experiment (EBEX), which was a balloon-borne instrumentdesigned to measure the polarization of the CMB as well as that from Galacticdust. The data show polarization fraction larger than 10\% while less than 3\%were expected from instrumental polarization. We give evidence that the excesspolarization is due to detector non-linearity in the presence of a continuouslyrotating HWP. The non-linearity couples intensity signals into polarization. Wedevelop a map-based method to remove the excess polarization. Applying thismethod for the 150 (250) GHz bands data we find that 81\% (92\%) of the excesspolarization was removed. Characterization and mitigation of this effect isimportant for future experiments aiming to measure the CMB B-modes with acontinuously rotating HWP.
