Detecting low-mass haloes with strong gravitational lensing II: constraints on the density profiles of two detected subhaloes
Giulia Despali, Felix M. Heinze, Christopher D. Fassnacht +3
Strong gravitational lensing can detect the presence of low-mass haloes and subhaloes through their effect on the surface brightness of lensed arcs. We carry out an extended analys…
TDCOSMO. XVI. Measurement of the Hubble Constant from the Lensed Quasar WGD20384008
Kenneth C. Wong, Frédéric Dux, Anowar J. Shajib +17
Time-delay cosmography is a powerful technique to constrain cosmological parameters, particularly the Hubble constant (). The TDCOSMO collaboration is performing an ongoing…
A Multiwavelength Portrait of the 3C 220.3 Lensed System
Sóley Ó. Hyman, Belinda J. Wilkes, S. P. Willner +10
The 3C 220.3 system is a rare case of a foreground narrow-line radio galaxy ("galaxy A," ) lensing a background submillimeter galaxy (). New spe…
General Multipoles and Their Implications for Dark Matter Inference
Jacob S. Cohen, Christopher D. Fassnacht, Conor M. O'Riordan +1
The flux ratios of strongly lensed quasars have previously been used to infer the properties of dark matter. In these analyses it is crucial to separate the effect of the main lens…
TDCOSMO XV: Population Analysis of Lines of Sight of 25 Strong Galaxy-Galaxy Lenses with Extreme Value Statistics
Patrick R. Wells, Christopher D. Fassnacht, Simon Birrer +1
Time-Delay Cosmography is a technique for measuring with strong gravitational lensing. It requires a correction for line of sight perturbations, and it is necessary to build…
