Exploring cosmic origins with CORE: gravitational lensing of the CMB
Anthony Challinor, Rupert Allison, Julien Carron +110
Lensing of the CMB is now a well-developed probe of large-scale clustering over a broad range of redshifts. By exploiting the non-Gaussian imprints of lensing in the polarization o…
Future CMB tests of dark matter: ultra-light axions and massive neutrinos
Renée Hložek, David J. E. Marsh, Daniel Grin +3
Measurements of cosmic microwave background (CMB) anisotropies provide strong evidence for the existence of dark matter and dark energy. They can also test its composition, probing…
Evidence of Lensing of the Cosmic Microwave Background by Dark Matter Halos
Mathew Madhavacheril, Neelima Sehgal, Rupert Allison +40
We present evidence of the gravitational lensing of the cosmic microwave background by solar mass dark matter halos. Lensing convergence maps from the Atacama Cosmology T…
The Atacama Cosmology Telescope: CMB Polarization at
Sigurd Naess, Matthew Hasselfield, Jeff McMahon +75
We report on measurements of the cosmic microwave background (CMB) and celestial polarization at 146 GHz made with the Atacama Cosmology Telescope Polarimeter (ACTPol) in its first…
Comparison of sampling techniques for Bayesian parameter estimation
Rupert Allison, Joanna Dunkley
The posterior probability distribution for a set of model parameters encodes all that the data have to tell us in the context of a given model; it is the fundamental quantity for B…
Bayesian evidence and predictivity of the inflationary paradigm
Giulia Gubitosi, Macarena Lagos, Joao Magueijo +1
In this paper we consider the issue of paradigm evaluation by applying Bayes' theorem along the following nested hierarchy of progressively more complex structures: i) parameter es…
