What Makes Quadruply Lensed Quasars Quadruple?
Richard Luhtaru, Paul L. Schechter, Kaylee M. de Soto
Among known strongly lensed quasar systems, ~25% have gravitational potentials sufficiently flat (and sources sufficiently well aligned) to produce four images rather than two. The…
High-resolution imaging follow-up of doubly imaged quasars
Anowar J. Shajib, Eden Molina, Adriano Agnello +8
We report upon three years of follow-up and confirmation of doubly imaged quasar lenses through imaging campaigns from 2016-2018 with the Near-Infrared Camera2 (NIRC2) on the W. M.…
Survey of Gravitationally lensed Objects in HSC Imaging (SuGOHI) -- VII. Discovery and Confirmation of Three Strongly Lensed Quasars
Anton T. Jaelani, Cristian E. Rusu, Issha Kayo +13
We present spectroscopic confirmation of three new two-image gravitationally lensed quasars, compiled from existing strong lens and X-ray catalogs. Images of HSC J091843.2702200…
Magnifications of paired micro-images emerging from a micro-lensing critical curve
Luke Weisenbach, Paul Schechter, Joachim Wambsganss
Studies of the inner regions of micro-lensed AGN during caustic crossing events have often relied upon the approximation that the magnification near a fold caustic is inversely pro…
Is every strong lens model unhappy in its own way? Uniform modelling of a sample of 13 quadruply+ imaged quasars
A. J. Shajib, S. Birrer, T. Treu +70
Strong-gravitational lens systems with quadruply-imaged quasars (quads) are unique probes to address several fundamental problems in cosmology and astrophysics. Although they are i…
A new quadruple-image gravitational lens in an edge-on disk galaxy at z=0.0956
John R. Lucey, Russell J. Smith, Paul L. Schechter +2
We report the serendipitous discovery of a quadruply-lensed source behind the z=0.095 edge-on disk galaxy 2MASXJ13170000-1405187, based on public imaging survey data from Pan-STARR…
