Gastaldello et al. analyze Chandra and XMM observations of poor clusters and find cool cores, a peak in temperature around 0.1 virial radii and decline. NFW model fits give concentration parameters and virial masses consistent with numerical simulations.

Done & Gierlinski show that an apparent highly relativistic line in XTE J1650 can be modelled by a relativistic line and Fe K line absorption from an outflowing disk wind - this allows the inner disk to be truncated.

Dave et al. provide an overview of current issues in galaxy formation theory.
