Diehl & Statler present results of analyzing Chandra observations of 54 normal ellipticals. They find little correlation between optical and X-ray emission and conclude that the X-ray emitting gas is generally out of equilibrium and does not retain information about the shape of the underlying potential.
Park et al. develop a Bayesian treatment of hardness ratios.
Wilman et al. present optical integrated field spectroscopy of the H-alpha luminous central galaxies in the four cooling flow clusters and find disturbed emission coincident with secondary galaxies.
Wickham et al. develop the use of reversible jump MCMC to study SMBH binary systems with LISA.
de Freitas Pacheco et al. estimate the capture rate of compact objects by SMBH.
Sanders presents a new technique for performing spatially-resolved spectroscopy by selecting regions based on surface-brightness contours of the smoothed image.
Loeb looks at thermal evaporation from clusters and notes this could lead to a loss of at least a tenth of the gas at the cluster virial temperature.
Schnittman et al. use relativistic MHD simulations of accretion onto a non-rotating BH to predict features of the high-frequency power spectrum.
Trimble et al. present their annual summary of the year in astrophysics.
Heinz et al. find using numerical simulations that radio source morphologies can be significantly changed by bulk flows in the cluster gas.
Beckmann et al. present the 20-40 keV AGN luminosity function based on Integral observations covering 25000 deg^2 and detecting 38 extragalactic objects.
Lauer et al. argue that for brightest cluster galaxies the BH mass correlation with bulge luminosity is more likely to be correct than that with bulge velocity dispersion.
Arun examines the differences in parameter estimation between 3.5PN and 2PN for LISA observations of BH mergers.
Babak et al. present "kludge" gravitational waveforms for compact objects inspiralling around massive black holes.
