All cosmological observations to date are consistent with adiabatic, Gaussian and nearly
scale invariant initial conditions. These findings provide strong evidence for a particular …

Since the discovery of the accelerated expansion of the present universe, significant
theoretical developments have been made in the area of modified gravity. In the meantime …

We present a sample-variance-limited measurement of the temperature power spectrum
(TT) of the cosmic microwave background using observations of a∼ 1500 deg 2 field made …

Determining the origin of structure in the universe is one of the most important open
problems in cosmology. CMB anisotropies sourced by early-universe density perturbations …

The past two decades have seen transformative advances in cosmology and string theory.
Observations of the cosmic microwave background have revealed strong evidence for …

We report a measurement of the B-mode polarization power spectrum in the cosmic
microwave background (CMB) using the Polarbear experiment in Chile. The faint B-mode …

ABSTRACT The Atacama Cosmology Telescope (ACT) makes high angular resolution
measurements of anisotropies in the Cosmic Microwave Background (CMB) at millimeter …

Gravitational lensing due to the large-scale distribution of matter in the cosmos distorts the
primordial cosmic microwave background (CMB) and thereby induces new, small-scale B …

We present a new study on the elastic scattering cross section of dark matter (DM) and
neutrinos using the latest cosmological data from Planck and large-scale structure …

CMB-S4 is a proposed experiment to map the polarization of the Cosmic Microwave
Background (CMB) to nearly the cosmic variance limit for angular scales that are accessible …
