We present millimeter-wave observations of three extra-galactic and sixGalactic sources in the Southern sky. Observations were made at 90, 150, 240and 400 GHz with resolutions of 18, 10, 14 and 12 arcmin respectively duringthe 1998 Antarctic long duration balloon flight of BOOMERANG. Observations werealso made with the SEST telescope, at 90 and 150 GHz with resolutions of 57 and35 arcsec respectively. These observations can be used for calibrations ofCosmic Microwave Background (CMB) experiments as well as an understanding ofthe physical processes of the sources.

Pogosyan D, Bond JR, Contaldi CR, 2003, Limits on the Dark Energy Parameters from Cosmic Microwave Background experiments

Full suite of the present day Cosmic Microwave background (CMB) data, whencombined with weak prior information on the Hubble constant and the age of theUniverse, or the Large-Scale structure, provides strong indication for anon-zero density of the vacuum-like dark energy in our universe. This resultindependently supports the conclusions from Supernovae Ia (SN1a) data. When themodel parameter space is extended to allow for the range of the equation ofstate parameter w_Q for the dynamical field Q which gives rise to dark energy,the CMB data is found to give a weak upper bound w_Q < -0.4 at 95% CL, howevercombined with SN1a data it strongly favours w_Q < -0.8, consistent withLambda-term like behaviour.

We review the recently published results from the CBI's first season ofobservations. Angular power spectra of the CMB were obtained from deepintegrations of 3 single fields covering a total of 3 deg^2 and 3 shallowersurveys of overlapping (mosaiced) fields covering a total of 40 deg^2. Theobservations show a damping of the anisotropies at high-l as expected from thestandard scenarios of recombination. We present parameter estimates obtainedfrom the data and discuss the significance of an excess at l>2000 observed inthe deep fields.

We derive cosmological parameters from the CBI measurements of the CosmicMicrowave Background (CMB) angular power spectrum. Our results provide anindependent confirmation of the standard $\Omega_{\rm tot}=1$ $\Lambda$CDMmodel within the adiabatic, inflationary paradigm. Above $\ell=2000$ theobservations show evidence of power in excess of that expected in the standardmodels. We use hydrodynamical simulations to show how Sunyaev-Zeldovich Effect(SZE) may account for the excess power for models with fluctuation amplitude$\sigma_8\sim 1$ which is in the high end of the range allowed by the primaryCMB observations.
