Luminous K-band Selected Quasars from UKIDSS
Natasha Maddox, Paul C. Hewett, S. J. Warren +1
The largest K-band flux-limited sample of luminous quasars to date has been constructed from the UKIDSS Large Area Survey Early Data Release, covering an effective area of 12.8 deg…
The OLS-lens survey: The discovery of five new galaxy-galaxy strong lenses from the SDSS
J. P. Willis, P. C. Hewett, S. J. Warren +2
Bright galaxy-galaxy strong lenses are much more powerful than lensed quasars for measuring the mass profiles of galaxies, but until this year only a handful have been known. Here…
Simulating Wide-Field Quasar Surveys from the Optical to Near-Infrared
Natasha Maddox, Paul C. Hewett
A number of deep, wide-field, near-infrared surveys employing new infrared cameras on 4m-class telescopes are about to commence. These surveys have the potential to determine the f…
Host galaxies of 2MASS-selected QSOs to redshift 0.3
J. B. Hutchings, N. Maddox, R. M. Cutri +1
We present and discuss optical imaging of 76 AGN which represent the 2MASS-selected sample for z<0.3, from a full list of 243. They are found to have dust-obscured nuclei, residing…
