Physics welcomes the idea that space contains energy whose gravitational effect
approximates that of Einstein's cosmological constant, Λ; today the concept is termed dark …

The observable universe could be a 1+ 3-surface (the “brane”) embedded in a 1+ 3+ d-
dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the …

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

Thanks to unparalleled near-horizon images of the shadows of Messier 87*(M87*) and
Sagittarius A*(Sgr A*) delivered by the Event Horizon Telescope (EHT), two amazing …

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 …

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

We present a simple mechanism for obtaining large-field inflation, and hence a gravitational
wave signature, from string theory compactified on twisted tori. For nil manifolds, we obtain a …

Recent work is reviewed in which compactifications of string and M theory are constructed in
which all scalar fields (moduli) are massive, and supersymmetry is broken with a small …

Kination denotes an era in the cosmological history corresponding to an equation of state
$\omega=+ 1$ such that the total energy density of the universe redshifts as the sixth inverse …
