The Quiescent Intracluster Medium in the Core of the Perseus Cluster
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +213
Clusters of galaxies are the most massive gravitationally-bound objects in the Universe and are still forming. They are thus important probes of cosmological parameters and a host…
SNR 1E 0102.2-7219 as an X-ray Calibration Standard in the 0.5-1.0 keV Bandpass and Its Application to the CCD Instruments aboard Chandra, Suzaku, Swift and XMM-Newton
Paul P. Plucinsky, Andrew P. Beardmore, Adam Foster +4
We desire a simple comparison of the absolute effective areas of the current generation of CCD instruments onboard the following observatories: Chandra ACIS-S3, XMM-Newton (EPIC-MO…
Hitomi constraints on the 3.5 keV line in the Perseus galaxy cluster
Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu +215
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 va…
Searching for the 3.5 keV Line in the Stacked Suzaku Observations of Galaxy Clusters
Esra Bulbul, Maxim Markevitch, Adam Foster +5
We perform a detailed study of the stacked Suzaku observations of 47 galaxy clusters, spanning a redshift range of 0.01-0.45, to search for the unidentified 3.5 keV line. This samp…
Radial Profile of the 3.55 keV line out to in the Perseus Cluster
Jeroen Franse, Esra Bulbul, Adam Foster +10
The recent discovery of the unidentified emission line at 3.55 keV in galaxies and clusters has attracted great interest from the community. As the origin of the line remains uncer…
