Cosmic Microwave Weak lensing data as a test for the dark universe
Erminia Calabrese, Anze Slosar, Alessandro Melchiorri +2
Combined analyses of WMAP 3-year and ACBAR Cosmic Microwave Anisotropies angular power spectra have presented evidence for gravitational lensing >3 sigma level. This signal could p…
An improved cosmological bound on the thermal axion mass
Alessandro Melchiorri, Olga Mena, Anze Slosar
Relic thermal axions could play the role of an extra hot dark matter component in cosmological structure formation theories. By combining the most recent observational data we impr…
Cross-correlation studies as a probe of reionization physics
Anze Slosar, Asantha Cooray, Joseph Silk
The process of reionization is now believed to have proceeded in an orchestrated manner beginning with UV photons emitted by high redshift galaxies containing a large fraction of P…
New Constraints on Oscillations in the Primordial Spectrum of Inflationary Perturbations
Jan Hamann, Laura Covi, Alessandro Melchiorri +1
We revisit the problem of constraining steps in the inflationary potential with cosmological data. We argue that a step in the inflationary potential produces qualitatively similar…
Estimating the bispectrum of the Very Small Array data
Sarah Smith, Graca Rocha, Anthony Challinor +30
We estimate the bispectrum of the Very Small Array data from the compact and extended configuration observations released in December 2002, and compare our results to those obtaine…
An improved Markov-chain Monte Carlo sampler for the estimation of cosmological parameters from CMB data
Anze Slosar, Michael Hobson
Markov-chain Monte Carlo sampling has become a standard technique for exploring the posterior distribution of cosmological parameters constrained by observations of CMB anisotropie…
