Free-Form and Hybrid Lens Models for SDSS J1004+4112: Substructure and Central Image Time Delay Constraints
Derek Perera, Liliya L. R. Williams, Jori Liesenborgs +2
SDSS J1004+4112 is a well studied gravitational lens with a recently measured time delay between its first and fourth arriving quasar images. Using this new constraint, we present…

Constraints on the Inner Regions of Lensing Galaxies from Central Images using a Recent AGN Offset Distribution
Derek Perera, Liliya L. R. Williams, Claudia Scarlata
In gravitational lensing, central images in quads can serve as a powerful probe of the inner regions of lens galaxies. The presence of an offset central supermassive black hole (SM…
