Abell 1201: The anatomy of a cold front cluster from combined optical and X-ray data
Matt S. Owers, Paul E. J. Nulsen, Warrick J. Couch +2
We present a combined X-ray and optical analysis of the cold front cluster Abell 1201 using archival Chandra, data and multi-object spectroscopy taken with the 3.9m Anglo Australia…
A low-frequency radio halo associated with a cluster of galaxies
G. Brunetti, S. Giacintucci, R. Cassano +7
Clusters of galaxies are the largest gravitationally bound objects in the Universe, containing about 10^15 solar masses of hot (10^8 K) gas, galaxies and dark matter in a typical v…
Impacts of a Supersonic Shock Front on Star Formation in the Bullet Cluster
Sun Mi Chung, Anthony H. Gonzalez, Douglas Clowe +3
We use the Bullet Cluster (1E0657-56) to investigate the extent to which star formation in cluster galaxies is influenced by ram pressure from supersonic gas (Mach 3) during a clus…
Shock acceleration as origin of the radio relic in A521?
S. Giacintucci, T. Venturi, G. Macario +6
We present new high sensitivity observations of the radio relic in A521 carried out with the Giant Metrewave Radio Telescope at 327 MHz and with the Very Large Array at 4.9 and 8.5…
A Multiply Imaged Luminous Infrared Galaxy Behind the Bullet Cluster
Anthony H. Gonzalez, Doug Clowe, Marusa Bradac +3
We present evidence for a Spitzer-selected luminous infrared galaxy (LIRG) behind the Bullet Cluster. The galaxy, originally identified in IRAC photometry as a multiply imaged sour…
Complex X-ray morphology of Abell 3128: A distant cluster behind a disturbed cluster
N. Werner, E. Churazov, A. Finoguenov +4
We present here the results of a detailed study of the X-ray properties of the cluster of galaxies Abell 3128 (z=0.06), based on the analysis of deep (100 ks) XMM-Newton data. The…
