Infrared Emission from the Nearby Cool Core Cluster Abell 2597
Megan Donahue, Andres Jordan, Stefi A. Baum +9
We observed the brightest central galaxy (BCG) in the nearby (z=0.0821) cool core galaxy cluster Abell 2597 with the IRAC and MIPS instruments on board the Spitzer Space Telescope.…
H-alpha tail, intracluster HII regions and star-formation: ESO137-001 in Abell 3627
M. Sun, M. Donahue, G. M. Voit
We present the discovery of a 40 kpc H-alpha tail and at least 29 emission-line objects downstream of a star-forming galaxy ESO 137-001 in the rich, nearby cluster A3627. The galax…
Star Formation, Radio Sources, Cooling X-ray Gas, and Galaxy Interactions in the Brightest Cluster Galaxy in 2A0335+096
Megan Donahue, Ming Sun, Christopher P. O'Dea +2
We present deep emission-line imaging taken with the SOAR Optical Imaging Camera of the brightest cluster galaxy (BCG) in the nearby (z=0.035) X-ray cluster 2A0335+096. We analyze…
The Representative XMM-Newton Cluster Structure Survey (REXCESS) of an X-ray Luminosity Selected Galaxy Cluster Sample
H. Boehringer, P. Schuecker, G. W. Pratt +31
The largest uncertainty for cosmological studies using clusters of galaxies is introduced by our limited knowledge of the statistics of galaxy cluster structure, and of the scaling…
Entropy generation in merging galaxy clusters
Michael Balogh, Ian McCarthy, Richard Bower +1
In McCarthy et al. (2007, astro-ph/0701335) we present an analysis of entropy generation during cluster mergers, using SPH simulations. This conference proceeding contribution summ…
Modelling Shock Heating in Cluster Mergers: I. Moving Beyond the Spherical Accretion Model
Ian G. McCarthy, Richard G. Bower, Michael L. Balogh +6
(Abridged) The thermal history of the intracluster medium (ICM) is complex. Heat input from cluster mergers, AGN, and galaxy winds offsets and may even halt the cooling of the ICM.…
