TL;DR: The examination of archival data revealing Faraday rotation in the fast radio burst FRB 110523 is reported, indicating magnetization in the vicinity of the source itself or within a host galaxy.
Journal ArticleDOI
An intensity map of hydrogen 21-cm emission at redshift z ≈ 0.8
TL;DR: A three-dimensional 21-cm intensity field is reported and neutral-hydrogen emission from the volumes surrounding about 10,000 galaxies (from the DEEP2 optical galaxy redshift survey) is co-added to detect the aggregate 21- cm glow at a significance of ∼4σ.
Journal ArticleDOI
Baryon Acoustic Oscillation Intensity Mapping of Dark Energy
TL;DR: In this paper, the authors show how the study of acoustic oscillation in the 21 cm brightness can be accomplished by economical three-dimensional intensity mapping, which is the starting point for a new class of dark energy experiments dedicated to large angular scale mapping of the radio sky, shedding light on dark energy.
Journal ArticleDOI
A simulation-calibrated limit on the H i power spectrum from the GMRT Epoch of Reionization experiment
Gregory Paciga,Joshua G. Albert,Kevin Bandura,Kevin Bandura,Tzu-Ching Chang,Tzu-Ching Chang,Yashwant Gupta,Christopher M. Hirata,Julia Odegova,Ue-Li Pen,Jeffrey B. Peterson,Jayanta Roy,J. Richard Shaw,Kris Sigurdson,Tabitha Voytek +14 more
TL;DR: In this paper, the authors explored the use of a singular value decomposition to remove foregrounds with fewer assumptions about the foreground structure and provided a revised measurement of a 2σ upper limit at (248 mK)^2 for k = 0.6.
Journal ArticleDOI
Measurement of 21 cm brightness fluctuations at z ~ 0.8 in cross-correlation

TL;DR: In this article, 21 cm intensity maps acquired at the Green Bank Telescope are cross-correlated with large-scale structure traced by galaxies in the WiggleZ Dark Energy Survey.
