Suzaku Observations of Low Surface Brightness Cluster Abell 1631

Yasunori Babazaki, Ikuyuki Mitsuishi, Naomi Ota +5

We present analysis results for a nearby galaxy cluster Abell 1631 at using the X-ray observatory Suzaku. This cluster is categorized as a low X-ray surface brightness…

Disturbed galaxy clusters are more abundant in an X-ray volume-limited sample

Gayoung Chon, Hans Boehringer

We present first strong observational evidence that the X-ray cool-core bias or the apparent bias in the abundance of relaxed clusters is absent in our REFLEX volume-limited sample…

The extended ROSAT-ESO Flux-Limited X-ray Galaxy Cluster Survey (REFLEX II) VII The Mass Function of Galaxy Clusters

Hans Boehringer, Gayoung Chon, Masataka Fukugita

The mass function of galaxy clusters is a sensitive tracer of the gravitational evolution of the cosmic large-scale structure and serves as an important census of the fraction of m…

Hot Gaseous Coronae around Spiral Galaxies: Probing the Illustris Simulation

Akos Bogdan, Mark Vogelsberger, Ralph P. Kraft +10

The presence of hot gaseous coronae around present-day massive spiral galaxies is a fundamental prediction of galaxy formation models. However, our observational knowledge remains…

Multiwavelength investigations of co-evolution of bright custer galaxies

Yasuhiro Hashimoto, J. Patrick Henry, Hans Boehringer

We report a systematic multi-wavelength investigation of environments of the brightest cluster galaxies (BCGs), using the X-ray data from the Chandra archive, and optical images ta…
