Population mixtures and searches of lensed and extended quasars across photometric surveys
Peter Williams, Adriano Agnello, Tommaso Treu
Wide-field photometric surveys enable searches of rare yet interesting objects, such as strongly lensed quasars or quasars with a bright host galaxy. Past searches for lensed quasa…
Strong lensing signatures of luminous structure and substructure in early-type galaxies
Daniel Gilman, Adriano Agnello, Tommaso Treu +2
The arrival times, positions, and fluxes of multiple images in strong lens systems can be used to infer the presence of dark subhalos in the deflector, and thus test predictions of…
H0LiCOW VI. Testing the fidelity of lensed quasar host galaxy reconstruction
Xuheng Ding, Kai Liao, Tommaso Treu +11
The empirical correlation between the mass of a super-massive black hole (MBH) and its host galaxy properties is widely considered to be evidence of their co-evolution. A powerful…
H0LiCOW I. Lenses in COSMOGRAIL's Wellspring: Program Overview
S. H. Suyu, V. Bonvin, F. Courbin +21
Strong gravitational lens systems with time delays between the multiple images allow measurements of time-delay distances, which are primarily sensitive to the Hubble constant that…
