Lazendic et al. present results from the analysis of a 70 ksec Chandra HETG observation of Cas A and describe the techniques used on such a large and complex target.
Loewenstein looks at heavy metal creation in field and cluster galaxies and concludes that star formation is >3 times as efficient in clusters as in the field, mitigating the overcooling problem.
Bogdanov et al. propose that the tail in the spectrum of rotation-powered millisecond pulsars is due to Comptonization of the thermal polar cap emission.
Benford models jets and magnetic bubbles to argue that magnetic structures can persist long after the jet has turned off and this explains the bubbles seen in the ICM.
Miller et al. show from X-ray observations of GRO J1655 that the absorbing wind must be driven by magnetic forces internal to the disk.
Blundell et al. determine the low-energy cutoff for the energy of relativistic particles accelerated in radio lobe hot spots.
Krivonos et al. analyze Integral observations of the Galactic Ridge and show that in spectrum and spatial distribution it is consistent with a population of accreting magnetic white dwarf binaries.
Saunders et al. discuss the optimal sampling strategy for searching for periodic signals.
Pizzolato and Soker argue that the R-T instability in radio bubbles in cooling flow clusters is stabilised by the deceleration of the interface in the initial expansion of the bubble increasing the expected lifetime.
Hogan detects the production of gravitational wave bursts by light cosmic strings.
