The inner density profile of an elliptical galaxy at z=1.15 from gravitational lensing
H. R. Stacey, C. M. O'Riordan, S. Vegetti +3
The density profiles of lensing galaxies are typically parameterised by singular power-law models with a logarithmic slope close to isothermal (). This is sufficient to fit th…
Joint constraints on thermal relic dark matter from strong gravitational lensing, the Lyman- forest, and Milky Way satellites
Wolfgang Enzi, Riccardo Murgia, Oliver Newton +10
We derive joint constraints on the warm dark matter (WDM) half-mode scale by combining the analyses of a selection of astrophysical probes: strong gravitational lensing with extend…
Systematic errors in strong gravitational lensing reconstructions, a numerical simulation perspective
W. Enzi, S. Vegetti, G. Despali +2
We present the analysis of a sample of twenty-four SLACS-like galaxy-galaxy strong gravitational lens systems with a background source and deflectors from the Illustris-1 simulatio…
The lensing properties of subhaloes in massive elliptical galaxies in sterile neutrino cosmologies
Giulia Despali, Mark Lovell, Simona Vegetti +2
We use high-resolution hydrodynamical simulations run with the EAGLE model of galaxy formation to study the differences between the properties of - and subsequently the lensing sig…
SHARP -- VII. New constraints on the dark matter free-streaming properties and substructure abundance from gravitationally lensed quasars
Jen-Wei Hsueh, Wolfgang Enzi, Simona Vegetti +5
We present an analysis of seven strongly gravitationally lensed quasars and the corresponding constraints on the properties of dark matter. Our results are derived by modelling the…
Constraining the mass density of free-floating black holes using razor-thin lensing arcs
Uddipan Banik, Frank C. van den Bosch, Michael Tremmel +5
Strong lensing of active galactic nuclei in the radio can result in razor-thin arcs, with a thickness of less than a milli-arcsecond, if observed at the resolution achievable with…
