A complete search for redshift z>6.5 quasars in the VIKING survey
R. Barnett, S. J. Warren, N. J. G. Cross +4
We present the results of a new, deeper, and complete search for high-redshift quasars over 977deg of the VISTA Kilo-Degree Infrared Galaxy (VIKING) survey. This ex…
Galaxy mass profiles from strong lensing III: The two-dimensional broken power-law model
Conor M. O'Riordan, Stephen J. Warren, Daniel J. Mortlock
When modelling strong gravitational lenses, i.e., where there are multiple images of the same source, the most widely used parameterisation for the mass profile in the lens galaxy…
Galaxy mass profiles from strong lensing II: The elliptical power-law model
Conor M. O'Riordan, Stephen J. Warren, Daniel J. Mortlock
We present a systematic analysis of the constraints on the mass profile slope obtainable when fitting a singular power-law ellipsoid model to a typical strong lensing obs…
