Dark-Matter Halos of Early-Type Galaxies
Philip J. Humphrey, David A. Buote, Fabio Gastaldello +4
Cosmological simulations of galaxy formation predict a universal form for the mass profile of dark matter (DM) halos from cluster to galaxy scales. Remarkably few interesting const…
Temperature and Dark Matter profiles of Galaxy Groups
F. Gastaldello, D. Buote, P. Humphrey +4
The Chandra and XMM data for a sample of 19 relaxed groups/poor clusters, covering the temperature range 1-3 keV and selected to have the best available data, reveal a remarkable s…
X-ray constraints on the dark matter profile of a very relaxed cluster of galaxies
L. Zappacosta, D. A. Buote, F. Gastaldello +4
We have analyzed an XMM-Newton observation of the cluster Abell 2589. Apart from a low-level asymmetry in the central region, the cluster appears very relaxed and does not show pre…
A changing inner radius in the accretion disc of Q0056-363?
G. Matt, D. Porquet, S. Bianchi +4
Q0056-363 is the most powerful X-ray quasar known to exhibit a broad, likely relativistic iron line (Porquet & Reeves 2003). It has been observed twice by XMM-, three and h…
Constraining the thermal history of the Warm-Hot Intergalactic Medium
L. Zappacosta, R. Maiolino, A. Finoguenov +3
We have identified a large-scale structure traced by galaxies at z=0.8, within the Lockman Hole, by means of multi-object spectroscopic observations. By using deep XMM images we ha…
