Merger of massive galaxy cluster CL0238.3+2005 at z~0.4: just after pericenter passage?
N. Lyskova, E. Churazov, I. Khabibullin +13
Massive clusters of galaxies are very rare in the observable Universe. Even rarer are mergers of such clusters observed close to pericenter passage. Here, we report on one such cas…
Extended X-ray study of M49: the frontier of the Virgo Cluster
Y. Su, R. P. Kraft, P. E. J. Nulsen +10
The M49 group, resident outside the virial radius of the Virgo cluster, is falling onto the cluster from the south. We report results from deep {\sl XMM-Newton} mosaic observations…
Stripped elliptical galaxies as probes of ICM physics: III. Deep Chandra Observation of NGC 4552 - Measuring the Viscosity of the Intracluster Medium
Ralph Kraft, Elke Roediger, Marie Machacek +7
We present results from a deep (200 ks) Chandra observation of the early-type galaxy NGC 4552 (M89) which is falling into the Virgo cluster. Previous shallower X-ray observations o…
Chandra and JVLA observations of HST Frontier Fields cluster MACS J0717.5+3745
R. J. van Weeren, G. A. Ogrean, C. Jones +24
To investigate the relationship between thermal and non-thermal components in merger galaxy clusters, we present deep JVLA and Chandra observations of the HST Frontier Fields clust…
Chandra deep observation of XDCP J0044.0-2033, a massive galaxy cluster at z>1.5
P. Tozzi, J. S. Santos, M. J. Jee +11
We report the analysis of the Chandra observation of XDCP J0044.0-2033, a massive, distant (z=1.579) galaxy cluster discovered in the XDCP survey. The total exposure time of 380 ks…
Chandra Observation of 3C288 - Reheating the Cool Core of a 3 keV Cluster from a Nuclear Outburst at z = 0.246
D. V. Lal, R. P. Kraft, W. R. Forman +6
We present results from a 42 ks Chandra/ACIS-S observation of the transitional FRI/FRII radio galaxy 3C288 at z = 0.246. We detect 3 keV gas extending to a radius of 0.…
Comparison of an approximately isothermal gravitational potentials of elliptical galaxies based on X-ray and optical data
E. Churazov, S. Tremaine, W. Forman +6
We analyze six X-ray bright elliptical galaxies, observed with Chandra and XMM-Newton, and approximate their gravitational potentials by isothermal spheres phi(r)=v_c^2 ln(r) over…
X-ray Constraints on Galaxy-Gas-Jet Interactions in the Dumbbell Galaxies NGC4782 and NGC4783 in the LGG316 Group
M. E. Machacek, R. P. Kraft, C. Jones +2
We present results from a 49.3 ks Chandra X-ray observation of the strongly interacting dumbbell galaxies NGC4782(3C278) and NGC4783 that constrain the kinematics of the interactio…
