Dust in galaxies can be mapped either by the FIR/submillimeter emission, the optical or infrared reddening of starlight, or the extinction of a known background source. ... We find that distant galaxies are predominantly in low-extinction sections marked by the color maps, indicating that their number depends both on the cloud cover of Spitzer-resolved dust structures, mostly the spiral arms, and a diffuse, unresolved underlying disk. ...

... QSO spectra in the ROSAT band are steeper than the background at harder energies, and furthermore at fluxes below 1E-14 ergs/(s cmќ) the quasar source counts flatten off and are replaced by more numerous populations of relatively low red-shift objects, apparently Narrow Emission Line Galaxies (NELG). ... We extracted the luminosity function from ROSAT Deep Survey results, and extrapolated by a factor of 2 - 3 to account for changes expected in the harder XMM band. ...

Constraints on Cosmological Models from Cosmic Flows M. J. Hudson et al. University of Waterloo, Canada Cosmic ows are the only probe of the large-scale mass power spectrum available at low redshift. An important statistic is the bulk ow of a peculiar velocity sample with respect to the Cos- mic Microwave background. We compare the bulk ow of the SMAC cluster sample to the predictions of popular cosmological models and to other recent large-scale peculiar velocity surveys. ...
