Cappi et al. present the results of an XMM survey of the nearest 27 Seyfert galaxies. The results are broadly in agreement with unification models with Sy 2 absorption columns ranging from 1e20 to 1e25 cm^-2.

Zhao et al. apply Bekenstein's relativistic version of MOND to gravitationa lens observations. They find a range of acceleration scales are required in violation of the assumption that this is a universal constant.

Lu & Love present a method for diverting an Earth-threatening asteroid using a spacecraft that hovers near the object. This eliminates the anchoring and rotation problems of a spacecraft pushing on the asteroid.

Diehl & Statler analyze archival Chandra observations of 30 early-type galaxies and find a relation between the X-ray temperature, half-light radius, and mean surface brightness. The width of this fundamental plane (0.07dex) is nearly identical to that of the stellar (optical) fundamental plane.

Atoyan et al. argue that HESS J1303-631, a bright, extended TeV source invisible at other wavelengths is the remnant of a long gamma-ray burst.

Stroeer et al. discuss what can be learned from LISA detections of interacting double WD binaries.

Seward et al. find no evidence for a thermal shell around the Crab Nebula from Chandra observations. The background consists of a dust scattering shell and mirror scattering.
The shell has L_X < 1e34 erg/s.

Watson et al. present the Swift X-ray spectrum and lightcurve of the z=6.29 GRB. In the first few minutes of the burst the apparent luminosity was 1e5-1e6 times that of the brightest high-z quasars.
