Joint Analysis of BICEP2/Keck Array and Planck Data

Peter A. R. Ade, +357 more
TL;DR: Strong evidence for dust and no statistically significant evidence for tensor modes is found and various model variations and extensions are probe, including adding a synchrotron component in combination with lower frequency data, and find that these make little difference to the r constraint.
Journal ArticleDOI

A gravitational-wave standard siren measurement of the Hubble constant

B. P. Abbott, +1322 more
- 02 Nov 2017 - 
TL;DR: A measurement of the Hubble constant is reported that combines the distance to the source inferred purely from the gravitational-wave signal with the recession velocity inferred from measurements of the redshift using the electromagnetic data.
Journal ArticleDOI

Improved Constraints on Cosmology and Foregrounds from BICEP2 and Keck Array Cosmic Microwave Background Data with Inclusion of 95 GHz Band

TL;DR: An analysis of all data taken by the BICEP2 and Keck Array cosmic microwave background (CMB) polarization experiments up to and including the 2014 observing season yields an upper limit r_{0.05}<0.09 at 95% confidence, which is robust to variations explored in analysis and priors.
Journal ArticleDOI

The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/Virgo GW170817. II. UV, Optical, and Near-infrared Light Curves and Comparison to Kilonova Models

Philip S. Cowperthwaite, +161 more
TL;DR: In this article, the Gordon and Betty Moore Foundation (GBMF5076) and the Heising-Simons Foundation (HSPF) have contributed to the creation of the DES-Brazil Consortium.
Journal ArticleDOI

The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/VIRGO GW170817. II. UV, Optical, and Near-IR Light Curves and Comparison to Kilonova Models

Philip S. Cowperthwaite, +99 more
TL;DR: In this article, the spectral energy distribution (SED) of the binary neutron star merger GW170817 was inferred from the optical and NIR spectrograms of the first electromagnetic counterpart to a gravitational wave source from Advanced LIGO/Virgo.
