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…
Observations of asymmetric velocity fields and gas cooling in the NGC 4636 galaxy group X-ray halo
Jussi Ahoranta, Alexis Finoguenov, Ciro Pinto +4
This study aims to probe the thermodynamic properties of the hot intragroup medium (IGM) plasma in the core regions of the NGC 4636 galaxy group by detailed measurements of several…
Insights into the location and dynamics of the coolest X-ray emitting gas in clusters of galaxies
Ciro Pinto, Andrew C. Fabian, Anna Ogorzalek +10
We extend our previous study of the cool gas responsible for the emission of OVII X-ray lines in the cores of clusters and groups of galaxies. This is the coolest X-ray emitting ph…
Chemical Enrichment RGS cluster sample (CHEERS): Constraints on turbulence
Ciro Pinto, Jeremy S. Sanders, Norbert Werner +6
Feedback from AGN, galactic mergers, and sloshing are thought to give rise to turbulence, which may prevent cooling in clusters. We aim to measure the turbulence in clusters of gal…
Discovery of O VII line emitting gas in elliptical galaxies
Ciro Pinto, Andrew C. Fabian, Norbert Werner +7
In the cores of ellipticals, clusters, and groups of galaxies, the gas has a cooling time shorter than 1 Gyr. It is possible to probe cooling flows through the detection of Fe XVII…
