Lens Model Accuracy in the Expected LSST Lensed AGN Sample
Padmavathi Venkatraman, Sydney Erickson, Phil Marshall +13
Strong gravitational lensing of active galactic nuclei (AGN) enables measurements of cosmological parameters through time-delay cosmography (TDC). With data from the upcoming LSST…
Analyzing Line-of-sight selection biases in galaxy-scale strong lensing with external convergence and shear
Xianzhe TZ Tang, Simon Birrer, Anowar J. Shajib +3
The upcoming Vera Rubin Observatory Legacy Survey of Space and Time (LSST) will dramatically increase the number of strong gravitational lensing systems, requiring precise modeling…
The Roman View of Strong Gravitational Lenses
Bryce Wedig, Tansu Daylan, Simon Birrer +13
Galaxy-galaxy strong gravitational lenses can constrain dark matter models and the Lambda Cold Dark Matter cosmological paradigm at sub-galactic scales. Currently, there is a deart…
A halo model approach for mock catalogs of time-variable strong gravitational lenses
Katsuya T. Abe, Masamune Oguri, Simon Birrer +5
Time delays in both galaxy- and cluster-scale strong gravitational lenses have recently attracted a lot of attention in the context of the Hubble tension. Future wide-field cadence…
