Strong Lensing by Galaxy Clusters
Priyamvada Natarajan, Liliya L. Williams, Marusa Bradac +4
Galaxy clusters as gravitational lenses play a unique role in astrophysics and cosmology: they permit mapping the dark matter distribution on a range of scales; they reveal the pro…
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…
What Multiple Images Say About the Large-Scale Mass Maps of Galaxy Clusters
Kekoa Lasko, Liliya L. R. Williams, Agniva Ghosh
All lens modeling methods, simply-parametrized, hybrid, and free-form, use assumptions to reconstruct galaxy clusters with multiply imaged sources, though the nature of these assum…
