The search for the curl component (B mode) in the cosmic microwave background (CMB)
polarization induced by inflationary gravitational waves is described. The canonical single …

Given the proliferation of bouncing models in recent years, we gather and critically assess
these proposals in a comprehensive review. The PLANCK data shows an unmistakably red …

We present results from an analysis of all data taken by the BICEP2, Keck Array, and
BICEP3 CMB polarization experiments up to and including the 2018 observing season. We …

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 present results from an analysis of all data taken by the bicep2/Keck CMB polarization
experiments up to and including the 2015 observing season. This includes the first Keck …

We present the implications for cosmic inflation of the Planck measurements of the cosmic
microwave background (CMB) anisotropies in both temperature and polarization based on …

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

Advanced ACTPol is a polarization-sensitive upgrade for the 6 m aperture Atacama
Cosmology Telescope, adding new frequencies and increasing sensitivity over the previous …

The polarized thermal emission from diffuse Galactic dust is the main foreground present in
measurements of the polarization of the cosmic microwave background (CMB) at …

We describe the design of a new polarization sensitive receiver, spt-3g, for the 10-meter
South Pole Telescope (spt). The spt-3g receiver will deliver a factor of~ 20 improvement in …
