A stochastic background of gravitational waves could be created by the superposition of a
large number of independent sources. The physical processes occurring at the earliest …

We review detection methods that are currently in use or have been proposed to search for a
stochastic background of gravitational radiation. We consider both Bayesian and frequentist …

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 …

A bstract We consider higher derivative corrections to the graviton three-point coupling
within a weakly coupled theory of gravity. Lorentz invariance allows further structures …

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 …

One century after its formulation, Einstein's general relativity (GR) has made remarkable
predictions and turned out to be compatible with all experimental tests. Most of these tests …

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 report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2
and Keck Array have observed the same approximately 400 deg 2 patch of sky centered on …

This paper presents cosmological results based on full-mission Planck observations of
temperature and polarization anisotropies of the cosmic microwave background (CMB) …

We present the current accounting of systematic effect uncertainties for the Low Frequency
Instrument (LFI) that are relevant to the 2015 release of the Planck cosmological results …
