Multiply imaged time-variable sources can be used to measure absolute distances as a
function of redshifts and thus determine cosmological parameters, chiefly the Hubble …

Strong gravitational lensing of quasars has the potential to unlock the poorly understood
physics of these fascinating objects, as well as serve as a probe of the lensing mass …

Gravitational time delays provide a powerful one-step measurement of H 0, independent of
all other probes. One key ingredient in time-delay cosmography are high-accuracy lens …

When strong gravitational lenses are to be used as an astrophysical or cosmological probe,
models of their mass distributions are often needed. We present a new, time-efficient …

Abstract On 2022 July 8, NASA shared (https://www. nasa. gov/feature/goddard/2022/nasa-
shares-list-of-cosmic-targets-for-webb-telescope-s-first-images) the list of five public …

Of order one in 10 3 quasars and high-redshift galaxies appears in the sky as multiple
images as a result of gravitational lensing by unrelated galaxies and clusters that happen to …

While most strong-gravitational-lensing systems may be roughly modelled by a single
massive object between the source and the observer, in the details all the structures near …

Strongly lensed systems with peculiar configurations allow us to probe the local properties of
the deflecting lens mass while simultaneously testing general profile assumptions. The …

Gravitationally lensed curved arcs provide a wealth of information about the underlying
lensing distortions. Extracting precise lensing information from extended sources is a key …

We present a mock catalog of gravitationally-lensed quasars at z qso< 7.5 with simulated
images for the Rubin Observatory Legacy Survey of Space and Time (LSST). We adopt …
