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…
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…
Primordial power spectrum and cosmology from black-box galaxy surveys
Florent Leclercq, Wolfgang Enzi, Jens Jasche +1
We propose a new, likelihood-free approach to inferring the primordial matter power spectrum and cosmological parameters from arbitrarily complex forward models of galaxy surveys w…
