We examine the gravitational redshift of radiation emitted from within the potential of a cluster. Spectral lines from the intracluster medium (ICM) are redshifted in proportion to the emission-weighted mean potential along the line of sigh...
Adaptive Optics Imaging of the CLASS Gravitational Lens System B1359+154 with the Canada-France-Hawaii Telescope [0.03%]

We investigate the weak gravitational lensing effect that is due to the large-scale structure of the universe on two-point correlations of local maxima (hot spots) in the two-dimensional sky map of the cosmic microwave background (CMB) anis...
Thomson Thick X-Ray Absorption in a Broad Absorption Line Quasar, PG 0946+301 [0.03%]

We present a deep ASCA observation of a broad absorption line quasar (BALQSO) PG 0946+301. The source was clearly detected in one of the gas imaging spectrometers, but not in any other detector. If BALQSOs have intrinsic X-ray spectra simil...

We identify high-density regions of supercluster size in high-resolution n-body simulations of a representative volume of three cold dark matter universes. By assuming that (1) the density and peculiar velocities of baryons trace those of t...
