Using a complete spectroscopic survey to find red quasars and test the KX method
Russell J. Jurek, Michael J. Drinkwater, Paul J. Francis +1
We present an investigation of quasar colour-redshift parameter space in order to search for radio-quiet red quasars and to test the ability of a variant of the KX quasar selection…
Luminous Red Galaxies in hierarchical cosmologies
C. Almeida, C. M. Baugh, D. A. Wake +4
Luminous red galaxies (LRGs) are much rarer and more massive than L* galaxies. Coupled with their extreme colours, LRGs therefore provide a demanding testing ground for the physics…
The WiggleZ project: AAOmega and Dark Energy
Karl Glazebrook, Chris Blake, Warrick Couch +16
We describe the `WiggleZ' spectroscopic survey of 280,000 star-forming galaxies selected from a combination of GALEX ultra-violet and SDSS + RCS2 optical imaging. The fundamental g…
Intrinsic galaxy alignments from the 2SLAQ and SDSS surveys: luminosity and redshift scalings and implications for weak lensing surveys
Christopher M. Hirata, Rachel Mandelbaum, Mustapha Ishak +5
Correlations between intrinsic shear and the density field on large scales, a potentially important contaminant for cosmic shear surveys, have been robustly detected at low redshif…
