THE SLOAN NEARBY CLUSTER WEAK LENSING SURVEY
(IOP PUBLISHING LTD, 2009)
We describe and present initial results of a weak lensing survey of nearby (z less than or similar to 0.1) galaxy clusters in the Sloan Digital Sky Survey (SDSS). In this first study, galaxy clusters are selected from the ...
Strong Gravitational Lensing by the Super-massive cD Galaxy in Abell 3827
(Iop Publishing, 2010-06)
We have discovered strong gravitational lensing features in the core of the nearby cluster Abell 3827 by analyzing Gemini South GMOS images. The most prominent strong lensing feature is a highly magnified, ring-shaped ...
Discovery of Four Gravitationally Lensed Quasars from the Sloan Digital Sky Survey
(2008)
We present the discovery of four gravitationally lensed quasars selected from the spectroscopic quasar catalog of the Sloan Digital Sky Survey (SDSS). We describe imaging and spectroscopic follow-up observations that support ...
On the cosmic distance duality relation and strong gravitational lens power law density profile
(2021-08-01)
Many new strong gravitational lensing (SGL) systems have been discovered in the last two decades with the advent of powerful new space and ground-based telescopes. The effect of the lens mass model (usually the power-law ...
Gravitational lensing and dynamics in SL2S J02140-0535: probing the mass out to large radius
(2011)
We aim to probe the mass of SL2S\,J02140-0535, a galaxy group at z = 0.44 from the Strong Lensing Legacy Survey (SL2S). We combine strong lensing modeling and dynamical constraints. The strong lensing analysis is based on ...
Evidence for two spatially separated UV continuum emitting regions in the Cloverleaf broad absorption line quasar
(EDP Sciences, 2015-10)
Testing the standard Shakura-Sunyaev model of accretion is a challenging task because the central region of quasars where accretion takes place is unresolved with telescopes. The analysis of microlensing in gravitationally ...
