Observing the Evolution of the Universe
James Aguirre, Alexandre Amblard, Amjad Ashoorioon +172
How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the univers…
The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background
S. Dodelson, R. Easther, S. Hanany +61
Modern cosmology has sharpened questions posed for millennia about the origin of our cosmic habitat. The age-old questions have been transformed into two pressing issues primed for…
Covariance of dark energy parameters and sound speed constraints from large HI surveys
A. Torres-Rodriguez, C. M. Cress, K. Moodley
An interesting probe of the nature of dark energy is the measure of its sound speed, . We review the significance for constraining sound speed models of dark energy using larg…
Measuring the geometry of the Universe in the presence of isocurvature modes
J. Dunkley, M. Bucher, P. G. Ferreira +2
The Cosmic Microwave Background (CMB) anisotropy constrains the geometry of the Universe because the positions of the acoustic peaks of the angular power spectrum depend strongly o…
Constraints on isocurvature models from the WMAP first-year data
K. Moodley, M. Bucher, J. Dunkley +2
We investigate the constraints imposed by the first-year WMAP CMB data extended to higher multipole by data from ACBAR, BOOMERANG, CBI and the VSA and by the LSS data from the 2dF…
Fast and reliable MCMC for cosmological parameter estimation
Joanna Dunkley, Martin Bucher, Pedro G. Ferreira +2
Markov Chain Monte Carlo (MCMC) techniques are now widely used for cosmological parameter estimation. Chains are generated to sample the posterior probability distribution obtained…
