Tegmark et al. present the cosmological results from the real-space power spectrum based on the SDSS luminous red galaxy survey. Baryon oscillations are clearly detected at a mean z=0.35.
Anderson et al. continue their work cross-correlating RASS sources with the SDSS to generate a large sample of X-ray emitting AGN.
Pratt et al. present temperature profiles from XMM observations of a representative sample of nearby clusters. Outside the core they find similar profiles which agree well with numerical simulations.
Hogan summarizes current ideas on gravitational wave tests for new physics.
Brewer et al. describe a Bayesian MCMC approach to extract stellar oscillation frequencies from light curves.
Elvis et al. describe an active-optics concept for making high resolution mirrors with low mass/unit area.
Poole et al. show the results of SPH simulations of mergers between idealised X-ray clusters. They reproduce the features observed in Chandra and XMM observations and note that neither of the compact cores of the merging clusters are disrupted.
Petric et al. put limits on extragalactic dust from the lack of a halo in a Chandra observation of a z=4.3 quasar.
Albrecht et al. is the report of the dark energy task force.
Wright describes a handy cosmology calculator for times and distances as a function of redshift.
