An Integrated System at the Bleien Observatory for Mapping the Galaxy

Posted by Chicago

Kavli Affiliate: Chihway Chang | First 5 Authors: Chihway Chang, Christian Monstein, Joel Akeret, Sebastian Seehars, Alexandre Refregier | Summary: We describe the design and performance of the hardware system at the Bleien Observatory. The system is designed to deliver a map of the Galaxy for studying the foreground contamination of low-redshift (z=0.13–0.43) H$_{rm I}$ […]

Hitomi constraints on the 3.5 keV line in the Perseus galaxy cluster

Posted by klaurent Stanford

Kavli Affiliate: Grzegorz M. Madejski | First 5 Authors: Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu, Fumie Akimoto, Steven W. Allen | Summary: High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of various massive systems, such as galaxies and […]
