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…

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 microlensing effect on time delays with new time-delay prediction model in measurements
Geoff C. -F. Chen, James H. H. Chan, Vivien Bonvin +14
Time-delay strong lensing provides a unique way to directly measure the Hubble constant (). The precision of the measurement depends on the uncertainties in the time…
