Journal ArticleDOI
Direct Observation of Cosmic Strings via their Strong Gravitational Lensing Effect: II. Results from the HST/ACS Image Archive
Eric Morganson,Phil Marshall,Phil Marshall,Tommaso Treu,Tim Schrabback,Tim Schrabback,Roger Blandford +6 more
TL;DR: In this paper, the authors search 4.5 square degrees of archival HST/ACS images for cosmic strings, identifying close pairs of similar, faint galaxies and selecting groups whose alignment is consistent with gravitational lensing by a long, straight string.

Book ChapterDOI
Gravitational Optics Studies of Dark Matter Halos
TL;DR: In this paper, it was shown that the large-scale mass to light ratio in red bandpasses is ∼ 100 solar units, and is apparently independent of galaxy type, and the prospects for improving the precision of these measurements and for extending them to larger length scales over the next five years are good.

TL;DR: In this paper, Hitomi observations of N 132 D, a young, X-ray bright, O-rich core-collapse supernova remnant in the Large Magellanic Cloud (LMC), were used to detect the line complexes of highly ionized S K and Fe K with 16-17 counts in each.
