BUFFALO Wild Wings: A High Precision Free-Form Lens Model of MACSJ0416 with Constraints on Dark Matter from Substructure and Highly Magnified Arcs
Derek Perera, Liliya L. R. Williams, Jori Liesenborgs +10
We present new free-form and hybrid mass reconstructions of the galaxy cluster lens MACS J0416.12403 at using the lens inversion method GRALE. The reconstructions use…

Reverberation mapping of high-mass and high-redshift quasars using gravitational time delays
Miriam Golubchik, Charles L. Steinhardt, Adi Zitrin +4
Mass estimates of black holes (BHs) in the centers of Active Galactic Nuclei (AGN) often rely on the radius-luminosity relation. However, this relation, usually probed by reverbera…
