Temperature Structure of Four Merging Clusters Obtained with Chandra
M. Markevitch, A. Vikhlinin, P. Mazzotta +1
We present preliminary Chandra results on z=0.2 clusters A665, A2163 and A2218, and a z=0.05 cluster A754. For A754, A665 and A2163, we have derived first high-resolution projected…
A moving cold front in the intergalactic medium of A3667
A. Vikhlinin, M. Markevitch, S. S. Murray
We present results from a Chandra observation of the central region of the galaxy cluster A3667, with emphasis on the prominent sharp X-ray brightness edge spanning 0.5 Mpc near th…
Chandra estimate of the magnetic field strength near the cold front in A3667
A. Vikhlinin, M. Markevitch, S. S. Murray
We use the Chandra observation of the cold front in the intracluster gas of A3667 to estimate the magnetic field strength near the front. The front is seen in the Chandra data as a…
Chandra Observation of Abell 2142: Survival of Dense Subcluster Cores in a Merger
M. Markevitch, T. J. Ponman, P. E. J. Nulsen +19
We use Chandra data to map the gas temperature in the central region of the merging cluster A2142. The cluster is markedly nonisothermal; it appears that the central cooling flow h…
X-ray total mass estimate for the nearby relaxed cluster A3571
J. Nevalainen, M. Markevitch, W. R. Forman
We constrain the total mass distribution in the cluster A3571, combining spatially resolved ASCA temperature data with ROSAT imaging data with the assumption that the cluster is in…
