The current cosmological model requires new physics beyond the standard model of
elementary particles and fields, such as dark matter and dark energy. Their nature is …

We search for evidence of parity-violating physics in the Planck 2018 polarization data and
report on a new measurement of the cosmic birefringence angle β. The previous …

We report on the implications for cosmic inflation of the 2018 release of the Planck cosmic
microwave background (CMB) anisotropy measurements. The results are fully consistent …

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 the temperature and polarization angular power spectra measured by the
Atacama Cosmology Telescope Polarimeter (ACTPol). We analyze night-time data collected …

The study of polarized dust emission has become entwined with the analysis of the cosmic
microwave background (CMB) polarization in the quest for the curl-like B-mode polarization …

Recent measurements of Galactic polarized dust emission have found a nonzero TB signal,
a correlation between the total intensity and the B-mode polarization component. We …

A detection of B-mode polarization of the cosmic microwave background (CMB) anisotropies
would confirm the presence of a primordial gravitational wave background (GWB). In the …

Spectral distortions of the cosmic microwave background (CMB) have been recognized as
an important future probe of the early Universe. Existing theoretical studies primarily focused …

If they exist, networks of superconducting cosmic strings are capable of injecting copious
amounts of electromagnetic energy into the background over a broad range of frequencies …
