TL;DR: In this article, the cosmological parameters derived from observations with the Cosmic Background Imager (CBI), covering 40 square degrees and the multipole range 300 < l < 3500, were reported.

TL;DR: In this paper, the authors estimate the accuracy with which various cosmological parameters can be determined from the cosmic microwave background (CMB) temperature and polarization data when various galactic unpolarized and polarized foregrounds are included and marginalized using the multi-frequency Wiener filtering technique.

TL;DR: In this article, the authors considered the Gumbel or extreme value statistics describing the distribution function pG(νmax) of the maximum values of a random field within patches of fixed size and showed that when the patch size becomes sufficiently large, the negative of the logarithm of the cumulative extreme value distribution is simply equal to the average of the Euler characteristic of the field in the excursion ν ≥ νmax inside the patches.

TL;DR: In this paper, a hydrodynamical simulation of galaxy formation is used to compute the number of high redshift objects as a function of luminosity, and yields galaxies whose UV luminosities closely match those measured in the deepest observational surveys available.

TL;DR: The Bayesian sampling algorithm for cosmology, CosmoPMC (Cosmology Population Monte Carlo), is presented, which explores the parameter space of various cosmological probes, and also provides a robust estimate of the Bayesian evidence.
