Submillimetre galaxies reside in dark matter haloes with masses greater than 3 × 10 11 solar masses

Alexandre Amblard, +84 more
TL;DR: Excess clustering over the linear prediction at arcminute angular scales in the power spectrum of brightness fluctuations at 250, 350 and 500 μm is reported, and it is found that submillimetre galaxies are located in dark matter haloes with a minimum mass, Mmin, which corresponds to the most efficient mass scale for star formation in the Universe.
Journal ArticleDOI

Quantifying discordance in the 2015 Planck CMB spectrum

TL;DR: In this article, the authors examined the internal consistency of the Planck 2015 cosmic microwave background (CMB) temperature anisotropy power spectrum and found that tension exists between cosmological constant cold dark matter (LCDM) model parameters inferred from multipoles l = 1000, particularly the CDM density, Omega_ch^2, which is discrepant at 2.5 sigma for a Planck-motivated prior on the optical depth, tau=0.07+/-0.02.
Journal ArticleDOI

First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Beam Profiles and Window Functions

TL;DR: In this paper, the authors presented the characterization of the in-flight optical response of the WMAP satellite, which is used for interpreting data from cosmic microwave background experiments and reported a calibration of Jupiter to 1-3% accuracy relative to the CMB dipole.
Journal ArticleDOI

BICEP2 / Keck Array V: Measurements of B-mode Polarization at Degree Angular Scales and 150 GHz by the Keck Array

TL;DR: In this paper, the authors report results from the 2012 and 2013 observing seasons, during which the Keck Array consisted of five receivers all operating in the same (150 GHz) frequency band and observing field as BICEP2.
