A Measurement of Gravitational Lensing of the Cosmic Microwave Background by Galaxy Clusters Using Data from the South Pole Telescope

E. J. Baxter, R. Keisler, S. Dodelson +72

Clusters of galaxies are expected to gravitationally lens the cosmic microwave background (CMB) and thereby generate a distinct signal in the CMB on arcminute scales. Measurements…

A Measurement of the Cosmic Microwave Background Gravitational Lensing Potential from 100 Square Degrees of SPTpol Data

K. T. Story, D. Hanson, P. A. R. Ade +63

We present a measurement of the cosmic microwave background (CMB) gravitational lensing potential using data from the first two seasons of observations with SPTpol, the polarizatio…

Evidence for interacting dark energy from BOSS

Elisa G. M. Ferreira, Jerome Quintin, André A. Costa +2

The result presented by the BOSS-SDSS Collaboration measuring the baryon acoustic oscillations of the Lyman- forest from high-redshift quasars indicates a departure from…

Measurements of E-Mode Polarization and Temperature-E-Mode Correlation in the Cosmic Microwave Background from 100 Square Degrees of SPTpol Data

A. T. Crites, J. W. Henning, P. A. R. Ade +63

We present measurements of -mode polarization and temperature--mode correlation in the cosmic microwave background (CMB) using data from the first season of observations with…

Consistency of dark matter interpretations of the 3.5 keV X-ray line

James M. Cline, Andrew R. Frey

Tentative evidence of a 3.5 keV X-ray line has been found in the stacked spectra of galaxy clusters, individual clusters, the Andromeda galaxy and the galactic center, leading to s…

Prospects for Delensing the Cosmic Microwave Background for Studying Inflation

Gabrielle Simard, Duncan Hanson, Gil Holder

A detection of excess cosmic microwave background (CMB) B-mode polarization on large scales allows the possibility of measuring not only the amplitude of these fluctuations but als…
