Feeney SM, Mortlock DJ, Dalmasso N, Clarifying the Hubble constant tension with a Bayesian hierarchical model of the local distance ladder

Estimates of the Hubble constant, $H_0$, from the local distance ladder andthe cosmic microwave background (CMB) are discrepant at the $\sim$3-$\sigma$level, indicating a potential issue with the standard $\Lambda$CDM cosmology.Interpreting this tension correctly requires a model comparison calculationwhich depends on not only the traditional `$n$-$\sigma$' mismatch but also thetails of the likelihoods. Determining the form of the tails of the local $H_0$likelihood is impossible with the standard Gaussian or least-squaresapproximation, as it requires using non-Gaussian distributions to faithfullyrepresent anchor likelihoods and model outliers in the Cepheid and supernova(SN) populations, and simultaneous fitting of the full distance-ladder datasetto ensure correct propagation of uncertainties. We have hence developed aBayesian hierarchical model that describes the full distance ladder, fromnearby geometric-distance anchors through Cepheids to SNe in the Hubble flow.This model does not rely on any underlying distributions being Gaussian,allowing outliers to be modeled and obviating the need for arbitrary data cuts.Sampling from the full $\sim$3000-parameter joint posterior using HamiltonianMonte Carlo, we find $H_0$ = (72.72 $\pm$ 1.67) ${\rm km\,s^{-1}\,Mpc^{-1}}$when applied to the outlier-cleaned Riess et al. (2016) data, and ($73.15 \pm1.78$) ${\rm km\,s^{-1}\,Mpc^{-1}}$ with SN outliers reintroduced. Ourhigh-fidelity sampling of the low-$H_0$ tail of the distance-ladder likelihoodallows us to apply Bayesian model comparison to assess the evidence fordeviation from $\Lambda$CDM. We set up this comparison to yield a lower limiton the odds of the underlying model being $\Lambda$CDM given thedistance-ladder and Planck Collaboration XIII (2016) CMB data. The odds against$\Lambda$CDM are at worst 10:1 or 7:1, depending on whether the SNe outliersare cut or modeled.

Mortlock DJ, Quasars as probes of cosmological reionization

Quasars are the most luminous non-transient sources in the epoch ofcosmological reionization (i.e., which ended a billion years after the BigBang, corresponding to a redshift of z ~ 5), and are powerful probes of theinter-galactic medium at that time. This review covers current efforts toidentify high-redshift quasars and how they have been used to constrain thereionization history. This includes a full description of the various processesby which neutral hydrogen atoms can absorb/scatter ultraviolet photons, andwhich lead to the Gunn-Peterson effect, dark gap and dark pixel analyses,quasar near zones and damping wing absorption. Finally, the future prospectsfor using quasars as probes of reionization are described.

Mortlock DJ, Bayesian model comparison in cosmology

The standard Bayesian model formalism comparison cannot be applied to mostcosmological models as they lack well-motivated parameter priors. However, ifthe data-set being used is separable then it is possible to use some of thedata to obtain the necessary parameter distributions, the rest of the databeing retained for model comparison. While such methods are not fullyprescriptive, they provide a route to applying Bayesian model comparison incosmological situations where it could not otherwise be used.

Mortlock DJ, Webster RL, Gravitational lensing in galaxy redshift surveys, 2001, in Gravitational Lensing: Recent Progress and Future Goals, Kochanek, C.S. & Brainerd, T.G., eds., Astronomical Society of the Pacific, San Francisco, 47

Gravitationally-lensed quasars should be discovered as a by-product of largegalaxy redshift surveys, being discovered spectroscopically when a low-redshiftgalaxy exhibits high-redshift quasar emission lines. The number of lensesexpected is higher than previously estimated, mainly due to the fact that thepresence of the quasar images brings faint deflector galaxies above the surveylimit. Thus the a posteriori likelihood of the discovery of Q 2237+0305 in theCenter for Astrophysics redshift survey is approximately 0.03. In the future,the 2 degree Field survey should yield at least 10 lensed quasars, and theSloan Digitial Sky Survey up to 100.

Mortlock DJ, Webster RL, The statistics of wide-separation lensed quasars, Mon.Not.Roy.Astron.Soc., Vol: 319

The absence of any wide-separation gravitational lenses in the Large BrightQuasar Survey is used to place limits on the population of cluster-sized halosin the universe, and hence constrain a number of cosmological parameters. Theresults agree with previous investigations in strongly ruling out the standardcold dark matter model but they are consistent with low-density universes inwhich the primordial fluctuation spectrum matches both cluster abundances andcosmic microwave background measurements. These conclusions are essentiallyindependent of the cosmological constant, which is in stark contrast to thestatistics of galaxy lenses. The constraints presented here are nullified ifclusters have core radii of more than 10 kpc, but are free of a number ofpotential systematic errors, due to the homogeneity of the data.

Mortlock DJ, Webster RL, Gravitational lensing by elliptical galaxies, Mon.Not.Roy.Astron.Soc., Vol: 319

The fraction of high-redshift sources which are multiply-imaged byintervening galaxies is strongly dependent on the cosmological constant, and socan be a useful probe of the cosmological model. However its power is limitedby various systematic (and random) uncertainties in the calculation of lensingprobabilities, one of the most important of which is the dynamicalnormalisation of elliptical galaxies. Assuming ellipticals' mass distributionscan be modelled as isothermal spheres, the mass normalisation depends on: thevelocity anisotropy; the luminosity density; the core radius; and the area overwhich the velocity dispersion is measured. The differences in the lensingprobability and optical depth produced by using the correct normalisation canbe comparable to the differences between even the most extreme cosmologicalmodels. The existing data is not sufficient to determine the correctnormalisation with enough certainty to allow lensing statistics to be used totheir full potential. However, as the correct lensing probability is almostcertainly higher than is usually assumed, upper bounds on the cosmologicalconstant are not weakened by these possibilities.

© Springer Science+Business Media New York 2013. All rights reserved. We present two statistical techniques for astronomical problems: a stargalaxy separator for the UKIRT Infrared Deep Sky Survey (UKIDSS) and a novel anomaly detection method for cross-matched astronomical datasets. The star-galaxy separator is a statistical classification method which outputs class membership probabilities rather than class labels and allows the use of prior knowledge about the source populations. Deep Sloan Digital Sky Survey (SDSS) data from the multiply imaged Stripe 82 region are used to check the results from our classifier, which compares favourably with the UKIDSS pipeline classification algorithm. The anomaly detection method addresses the problem posed by objects having different sets of recorded variables in cross-matched datasets. This prevents the use of methods unable to handle missing values and makes direct comparison between objects difficult. For each source, our method computes anomaly scores in subspaces of the observed feature space and combines them to an overall anomaly score. The proposed technique is very general and can easily be used in applications other than astronomy. The properties and performance of our method are investigated using both real and simulated datasets.
