Gravitational lensing and elliptical galaxies
Daniel J. Mortlock, Rachel L. Webster
If the statistics of quasar lensing are to be used to constrain the cosmological model, the various potential systematic uncertainties in the deflector population must be accounted…
Gravitational lensing in galaxy redshift surveys
Daniel J. Mortlock, Rachel L. Webster
Gravitationally-lensed quasars should be discovered as a by-product of large galaxy redshift surveys, being discovered spectroscopically when a low-redshift galaxy exhibits high-re…
The statistics of wide-separation lenses
Daniel J. Mortlock
The probability that high-redshift sources are gravitationally-lensed with large image separations (i.e., greater than can be produced by galactic deflectors) is determined by the…
Using the 2dF galaxy redshift survey to detect gravitationally-lensed quasars
Daniel J. Mortlock, Rachel L. Webster
Galaxy redshift surveys can be used to detect gravitationally-lensed quasars if the spectra obtained are searched for the quasars' emission lines. Previous investigations of this p…
All-sky convolution for polarimetry experiments
Anthony Challinor, Pablo Fosalba, Daniel Mortlock +3
We discuss all-sky convolution of the instrument beam with the sky signal in polarimetry experiments, such as the Planck mission which will map the temperature anisotropy and polar…
Using galaxy redshift surveys to detect gravitationally-lensed quasars
Daniel J. Mortlock, Rachel L. Webster
Gravitationally-lensed quasars can be discovered as a by-product of galaxy redshift surveys. Lenses discovered spectroscopically in this way should require less observational effor…
