Strong gravitational lensing's 'external shear' is not shear
Amy Etherington, James W. Nightingale, Richard Massey +19
The distribution of mass in galaxy-scale strong gravitational lenses is often modelled as an elliptical power law plus 'external shear', which notionally accounts for neighbouring…
Constraints on dark matter self-interaction from the internal density profiles of X-COP galaxy clusters
D. Eckert, S. Ettori, A. Robertson +4
TThe fundamental properties of the postulated dark matter (DM) affect the internal structure of gravitationally-bound structures. In the cold dark matter paradigm, DM particles int…
PyAutoLens: Open-Source Strong Gravitational Lensing
James. W. Nightingale, Richard G. Hayes, Ashley Kelly +14
Strong gravitational lensing, which can make a background source galaxy appears multiple times due to its light rays being deflected by the mass of one or more foreground lens gala…
The impact of Self-Interacting Dark Matter on the Intrinsic Alignments of Galaxies
David Harvey, Nora Elisa Chisari, Andrew Robertson +1
The formation and evolution of galaxies is known to be sensitive to tidal processes leading to intrinsic correlations between their shapes and orientations. Such correlations can b…
A 4% measurement of using the cumulative distribution of strong-lensing time delays in doubly-imaged quasars
David Harvey
In the advent of large scale surveys, individually modelling strong-gravitational lenses and their counterpart time-delays in order to precisely measure will become computati…
Reconciling galaxy cluster shapes, measured by theorists vs observers
David Harvey, Andrew Robertson, Sut-Ieng Tam +4
If properly calibrated, the shapes of galaxy clusters can be used to investigate many physical processes: from feedback and quenching of star formation, to the nature of dark matte…
