Kunz et al. introduce Bayesian complexity to assess how many effective parameters a data set can support.
Rasia et al. use five simulated galaxy clusters to investigate systematics in the determination of the total mass using X-ray observations.
Martini et al. survey 8 low-z clusters of galaxies for X-ray AGN and conclude that cluster galaxies host an AGN with a much higher frequency than supposed from optical observations.
Davis & Hubeny describe their relativistic, non-LTE atmosphere models for accretion disks in BH binaries.
Bregman & Lloyd-Davies conclude that the soft-excesses seen in clusters using XMM are not associated with the clusters but with Galactic features.
Allen et al. demonstrate a correlation between the Bondi accretion rate and the AGN jet power using Chandra data on 9 nearby ellipticals.
