The cluster environments of radio loud quasars
J. M. Barr, M. N. Bremer, J. C. Baker +1
We have carried out multi-colour imaging of the fields of a statistically complete sample of low-frequency selected radio loud quasars at 0.6<z<1.1, in order to determine the chara…
Associated absorption and radio source growth
Joanne C. Baker
Results are presented from a survey for CIV associated absorption in a complete low-frequency-selected sample of quasars. In agreement with previous work, associated absorbers are…
The environments of radio-loud quasars
J. M. Barr, M. N. Bremer, J. C. Baker
We have obtained multi-colour imaging of a representative, statistically complete sample of low-frequency selected (S_408MHz > 0.95Jy) radio loud quasars at intermediate (0.6 < z <…
Completeness and confusion in the identification of Lyman-break galaxies
Garret Cotter, Toby Haynes, Joanne C. Baker +2
We have carried out a study to simulate distant clusters of galaxies in deep ground-based optical images. We find that when model galaxies are added to deep images obtained with th…
WOMBAT & FORECAST: Making Realistic Maps of the Microwave Sky
Andrew H. Jaffe, Eric Gawiser, Douglas Finkbeiner +11
The Wavelength-Oriented Microwave Background Analysis Team (WOMBAT) is constructing microwave maps which will be more realistic than previous simulations. Our foreground models rep…
The WOMBAT Challenge: A "Hounds and Hares" Exercise for Cosmology
Eric Gawiser, Douglas Finkbeiner, Andrew Jaffe +10
The Wavelength-Oriented Microwave Background Analysis Team (WOMBAT) is constructing microwave skymaps which will be more realistic than previous simulations. Our foreground models…
