The detection of the accelerated expansion of the Universe has been one of the major
breakthroughs in modern cosmology. Several cosmological probes (Cosmic Microwave …

Liquid crystals are widely known for their technological uses in displays, electro-optics,
photonics and nonlinear optics, but these applications typically rely on defining and …

Cadenced optical imaging surveys in the next decade will be capable of detecting time-
varying galaxy-scale strong gravitational lenses in large numbers, increasing the size of the …

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 …

We study the mass distribution of a sample of 28 galaxy clusters using strong and weak
lensing observations. The clusters are selected via their strong lensing properties as part of …

We present the final statistical sample of lensed quasars from the Sloan Digital Sky Survey
(SDSS) Quasar Lens Search (SQLS). The well-defined statistical lens sample consists of 26 …

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 …

We present a method of calculating the strong-field gravitational lensing caused by many
analytic and numerical spacetimes. We use this procedure to calculate the distortion caused …

We present new light curves for the four bright images of the five image cluster-lensed
quasar gravitational lens system SDSS J1004+ 4112. The light curves span 14.5 yr and …

Gravitational microlensing is a powerful tool for probing the physical properties of quasar
accretion disks and properties of the lens galaxy such as its dark matter fraction and mean …
