Suzaku observation of a high entropy cluster Abell 548W
Kazuhiro Nakazawa, Yuichi Kato, Liyi Gu +4
Abell 548W, one of the galaxy clusters located in the Abell 548 region, has about an order of magnitude lower X-ray luminosity compared to ordinal clusters in view of the well know…
A novel scenario for the possible X-ray line feature at ~3.5 keV: Charge exchange with bare sulfur ions
L. Gu, J. Kaastra, A. J. J. Raassen +4
Motivated by recent claims of a compelling ~3.5 keV emission line from nearby galaxies and galaxy clusters, we investigate a novel plasma model incorporating a charge exchange comp…
Discovery of a nearby early-phase major cluster merger CIZA J1358.9-4750
Yuichi Kato, Kazuhiro Nakazawa, Liyi Gu +4
CIZA J1358.9-4750 is a nearby (z = 0.074) pair of clusters of galaxies located close to the Galactic plane. It consists of two X-Ray extended humps at north-west and south-east sep…
