Wyithe & Loeb argue that SMBH growth rate is determined by the spheroid velocity dispersion, not the mass.
Cornish & Crowder test MCMC methods for LISA data analysis.
Bertolami & Vieira test various models of the Kuiper belt to see whether they can explain the Pioneer Anomaly. None work however they note that any mission to test the anomaly will also be a useful probe of the mass distribution in the belt.
McKernan et al. place limits on ionic column densities of Galactic halo hot gas using Chandra grating spectral observations of 15 type I AGN.
Tagliaferri et al. summarize the prompt X-ray emission lightcurve from Swift bursts.
Dupke & Bregman survey constraints on bulk motions in clusters based on ASCA spectra.
Read et al. describe progress towards the XMM slew-survey which will cover the sky at 2-10 keV ten times deeper than all other surveys in this energy range.
Vaughan & Uttley consider what is required to detect QPOs from AGN and conclude that the most efficient technique requires and all-sky version of the RXTE ASM.
