Bregman shows that a claimed relationship between radio, X-ray luminosity, and BH mass in AGN is an artefact of the flux-limited sample.
Armus et al. find evidence with Spitzer for an AGN in NGC 6240 - consistent with the hard X-ray results.
Stuhlinger et al. summarize the status of XMM-Newton calibration.
Donahue et al. present Chandra entropy profiles of 9 cooling flow clusters and find the profiles are similar over a range of 3 in temperature.
Ghizzardi et al. find cold fronts in 21 out of 62 clusters searched using XMM data.
