McHardy et al. argue on the basis of X-ray variability and optical emission line widths that AGN are just scaled-up galactic binaries in terms of their black hole accretion process.

Schaefer constructs a Hubble diagram from 69 GRBs and argues that it provides an accuracy only a factor of 2 worse than the big SNIa surveys.

Boyarsky et al. note that improved limits on the sterile neutrino can be obtained using a wide-field but low effective area (ie no telescope) calorimeter.

Ravikumar et al. present new redshifts of objects in the CDFS (alias GOODS-South) and note that this field contains anomalous structures containing evolved, massive galaxies.

Barack & Cutler investigate how well LISA observations of EMRIs can test that spacetime around a rotating BH is the Kerr metric.

Wise et al. report on a deep Chandra observation of Hydra A which shows extensive cavities which correlate precisely with 330 MHz emission.

Belczynski et al. argue that the creation of stellar mass BH binaries are suppressed by mergers during the common envelope phase and so these are not likely to be a significant population for advanced LIGO.

Andersson et al. use their new Smoothed Particle Inference technique to derive temperature maps of three clusters observed using XMM.
