We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

Neutrinos are the only particles in the Standard Model (SM) of particle physics that have only
been observed with left handed chirality to date. If right handed (RH) neutrinos exist, they …

We describe the legacy Planck cosmic microwave background (CMB) likelihoods derived
from the 2018 data release. The overall approach is similar in spirit to the one retained for …

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 …

We present the temperature and polarization angular power spectra of the CMB measured
by the Atacama Cosmology Telescope (ACT) from 5400 deg 2 of the 2013–2016 survey …

We present cosmological parameter results from the final full-mission Planck measurements
of the cosmic microwave background (CMB) anisotropies, combining information from the …

The Simons Observatory (SO) is a new cosmic microwave background experiment being
built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the …

MontePython is a parameter inference package for cosmology. We present the latest
development of the code over the past couple of years. We explain, in particular, two new …

This paper presents the Planck 2015 likelihoods, statistical descriptions of the 2-point
correlationfunctions of the cosmic microwave background (CMB) temperature and …
