Kinematic unrest of low mass galaxy groups
G. Gozaliasl, A. Finoguenov, H. G. Khosroshahi +6
In an effort to better understand the formation of galaxy groups, we examine the kinematics of a large sample of spectroscopically confirmed X-ray galaxy groups in the Cosmic Evolu…
Hot WHIM counterparts of FUV OVI absorbers: Evidence in the line-of-sight towards quasar 3C 273
Jussi Ahoranta, Jukka Nevalainen, Nastasha Wijers +7
We explore the high spectral resolution X-ray data towards the quasar 3C273 to search for signals of hot ( K) X-ray-absorbing gas co-located with two established inte…
New Chandra observations of PG 1116+215 to investigate an extragalactic OVIII WHIM absorption line
Massimiliano Bonamente, Jussi Ahoranta, Jukka Nevalainen +1
This is a short AAS Research Note on the analysis of new Chandra observations of PG 1116+215, for which an extragalactic OVIII WHIM line was reported by Bonamente et al. (2016). Th…
Chandra centres for COSMOS X-ray galaxy groups: Differences in stellar properties between central dominant and offset brightest group galaxies
Ghassem Gozaliasl, Alexis Finoguenov, Masayuki Tanaka +24
We present the results of a search for galaxy clusters and groups in the square degree of the COSMOS field using all available X-ray observations from the XMM-Newton and Ch…
To be or not to be: hot WHIM absorption in the blazar PKS 2155-304 sight line?
J. Nevalainen, E. Tempel, J. Ahoranta +8
The cosmological missing baryons at z<1 most likely hide in the hot (T K) phase of the Warm Hot Intergalactic Medium (WHIM). While the hot WHIM is hard to detect d…
CHEERS: The chemical evolution RGS sample
J. de Plaa, J. S. Kaastra, N. Werner +17
The chemical yields of supernovae and the metal enrichment of the hot intra-cluster medium (ICM) are not well understood. This paper introduces the CHEmical Enrichment RGS Sample (…
