Strong lensing is a powerful tool to address three major astrophysical issues: understanding
the spatial distribution of mass at kiloparsec and subkiloparsec scale, where baryons and …

We present a strong lens analysis of SDSS J1004 4112, a unique quasar lens produced by
a massive cluster of galaxies at 0.68, using newly developed software for gravitational …

In the present-day universe, supermassive black hole masses (Script M BH) appear to be
strongly correlated with their galaxy's bulge luminosity, among other properties. In this study …

In the context of gravitational lensing, the density profile of lensing galaxies is often
considered to be perfectly elliptical. Potential angular structures are generally ignored …

Strong-gravitational lens systems with quadruply imaged quasars (quads) are unique
probes to address several fundamental problems in cosmology and astrophysics. Although …

We present a strong lensing modeling technique based on versatile basis sets for the lens
and source planes. Our method uses high performance Monte Carlo algorithms, allows for …

As a fundamental parameter for modern cosmology, the Hubble constant H 0 is
experiencing a serious crisis. In this paper, we explore an independent approach to …

Strong gravitational lenses can be used to detect low-mass subhaloes, based on deviations
in image fluxes and positions from what can be achieved with a smooth mass distribution …

I review methods for modeling gravitational lens systems comprising multiple images of a
background source surrounding a foreground galaxy. In a Bayesian framework, the …

Discrepancies between the observed and model-predicted radio flux ratios are seen in a
number of quadruply-lensed quasars. The most favoured interpretation of these anomalies …
