The 2dF-SDSS LRG and QSO Survey: The spectroscopic QSO catalogue
Scott M. Croom, Gordon T. Richards, Tom Shanks +27
We present the final spectroscopic QSO catalogue from the 2dF-SDSS LRG and QSO (2SLAQ) Survey. This is a deep, 18<g<21.85 (extinction corrected), sample aimed at probing in detail…
A Full Year's Chandra Exposure on SDSS Quasars from the Chandra Multiwavelength Project
Paul J. Green, T. L. Aldcroft, G. T. Richards +13
We study the spectral energy distributions and evolution of a large sample of optically selected quasars from the Sloan Digital Sky Survey (SDSS) that were observed in 323 Chandra…
Gravitational Dynamics of Large Stellar Systems
Stephen L. W. McMillan
Internal dynamical evolution can drive stellar systems into states of high central density. For many star clusters and galactic nuclei, the time scale on which this occurs is signi…
Seoul National University Bright Quasar Survey in Optical (SNUQSO) I: First Phase Observations and Results
Induk Lee, Myungshin Im, Minjin Kim +7
We present results from the first phase of the Seoul National University Bright Quasar Survey in Optical (SNUQSO) as well as its basic observational setup. Previous and current lar…
Average Properties of a Large Sample of z_abs ~ z_em associated Mg II Absorption Line Systems
D. Vanden Berk, P. Khare, D. G. York +16
We have studied a sample of 415 associated (z_ab z_em; relative velocity with respect to QSO <3000km/s) Mg II absorption systems with 1.0<=z_ab<=1.86, in the spectra of SDSS DR3 QS…
Combined analysis of the integrated Sachs-Wolfe effect and cosmological implications
Tommaso Giannantonio, Ryan Scranton, Robert G. Crittenden +4
We present a global measurement of the integrated Sachs-Wolfe (ISW) effect obtained by cross-correlating all relevant large scale galaxy data sets with the cosmic microwave backgro…
