Stanek proposes a an alternative history version of astro-ph for failed telescope and other proposals. Probably should have come out on Apr 1.
Feroz & Hobson describe an efficient sampling method for multimodel and/or degenerate distributions when calculating Bayesian evidence.
Hallman et al. use numerical simulations to show that using beta-model fits to X-ray data in the analysis of SZE observations leads to systematic biases and suggest a simple correction.
Miller reviews relativistic X-ray lines from the inner regions of accretion disks.
Magliocchetti & Bruggen combine X-ray data from the REFLEX and NORAS samples and radio data from the NVSS to investigate the effects of radio sources on the cluster L_X-T relation.
Kitaura & Ensslin survey Bayesian reconstruction schemes for large-scale structure.
Kerkyacharian et al. present a new estimation method for the inverse problem building on SVD decomposition.
