Elucidating ΛCDM: Impact of Baryon Acoustic Oscillation Measurements on the Hubble Constant Discrepancy
Graeme E. Addison,Duncan J. Watts,Charles L. Bennett,Mark Halpern,Gary Hinshaw,Janet Weiland +5 more
TL;DR: In this article, the authors examined the impact of baryon acoustic oscillation (BAO) scale measurements on the discrepancy between the value of the Hubble constant inferred from the local distance ladder and from Planck cosmic microwave background (CMB) data.

TL;DR: In this paper, the authors reported the detection of a $16.35\pm 0.15$ day periodicity (or possibly a higher-frequency alias of that periodicity) from a repeating fast radio burst (FRB) 180916.J0158+65 detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB).
Journal ArticleDOI
Seven-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Sky Maps, Systematic Errors, and Basic Results
N. Jarosik,Charles L. Bennett,Joanna Dunkley,B. Gold,M. R. Greason,Mark Halpern,Robert S. Hill,Gary Hinshaw,Alan J. Kogut,Eiichiro Komatsu,Davin Larson,Michele Limon,S. S. Meyer,Michael R. Nolta,N. Odegard,Lyman A. Page,Kristine M. Smith,David N. Spergel,Gregory S. Tucker,Janet L. Weiland,Edward J. Wollack,Edward L. Wright +21 more
TL;DR: In this article, the authors presented a new full sky temperature and polarization maps based on seven years of data from WMAP, which are consistent with previous results, but have improved due to reduced noise from the additional integration time, improved knowledge of the instrument performance, and improved data analysis procedures.
Journal ArticleDOI
The HDF-North SCUBA Super-map I: Submillimetre maps, sources and number counts
TL;DR: In this article, the authors investigated the emission of sub-millimetre-wave radiation from galaxies in a 165 square arcminute region surrounding the Hubble Deep Field North, and presented a new estimate of the 850 micron and 450 micron source counts.
