Andromeda’s Parachute: Time Delays and Hubble Constant
The Astrophysical Journal, 2023 The gravitational lens system PS J0147+4630 (Andromeda’s Parachute) consists of four quasar images ABCD and a lensing galaxy. We obtained r -band light curves of ABCD in the 2017−2022 period from monitoring with two 2 m class telescopes.

Strong gravitational lensing of explosive transients [PDF]
Reports on Progress in Physics, 2019 Abstract Recent rapid progress in time domain surveys makes it possible to detect various types of explosive transients in the Universe in large numbers, some of which will be gravitationally lensed into multiple images. Although a large number of strongly lensed distant galaxies and quasars have already been discovered, strong ...

Combined strong and weak gravitational lensing mass measurements in clusters of galaxies [PDF]
, 2022 Gravitational lensing in clusters of galaxies is one of the most powerful methods to probe the dark matter mass distribution inside such systems, after mapping the baryonic component, and test the currently accepted ΛCDM cosmological paradigm.

Searching for Strong Gravitational Lenses
Space Science ReviewsAbstractStrong gravitational lenses provide unique laboratories for cosmological and astrophysical investigations, but they must first be discovered – a task that can be met with significant contamination by other astrophysical objects and asterisms.

Strong gravitational lensing by Kiselev black hole [PDF]
Physical Review D, 2015 We investigate the gravitational lensing scenario due to Schwarzschild-like black hole surrounded by quintessence (Kiselev black hole). We work for the special case of Kiselev black hole where we take the state parameter $w_{q}=-\frac{2}{3}$. For the detailed derivation and analysis of the bending angle involved in the deflection of light, we discuss ...

Precision Modeling of JWST's First Cluster Lens SMACS J0723.3–7327
The Astrophysical Journal, 2023 Exploiting the fundamentally achromatic nature of gravitational lensing, we present a lens model for the massive galaxy cluster SMACS J0723.3−7323 (SMACS J0723; z = 0.388) that significantly improves upon earlier work.

STRONG GRAVITATIONAL LENSING AND ITS COSMIC CONSTRAINTS [PDF]
Modern Physics Letters A, 2013 In this paper, we propose a new method to use the strong lensing data sets to constrain a cosmological model. By taking the ratio [Formula: see text] as cosmic observations, one can completely eliminate the uncertainty caused by the relation σSIS= fEσ0which characterizes the relation between the stellar velocity dispersion σ0and the velocity dispersion
