Search for Gravitational-lensing Signatures in the Full Third Observing Run of the LIGO–Virgo Network [PDF]

open access: yesAstrophysical Journal, 2023
Gravitational lensing by massive objects along the line of sight to the source causes distortions to gravitational wave (GW) signals; such distortions may reveal information about fundamental physics, cosmology, and astrophysics.

Strong Gravitational Lensing as a Probe of Dark Matter [PDF]

open access: yesSpace Science Reviews, 2023
Dark matter structures within strong gravitational lens galaxies and along their lines of sight leave a gravitational imprint on the multiple images of lensed sources.

lenstronomy II: A gravitational lensing software ecosystem [PDF]

open access: yesJournal of Open Source Software, 2021
lenstronomy is an Astropy-affiliated Python package for gravitational lensing simulations and analyses. lenstronomy was introduced by Birrer and Amara (2018) and is based on the linear basis set approach by Birrer et a. (2015).

Strong gravitational lensing by rotating Simpson-Visser black holes [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2021
We investigate strong field gravitational lensing by rotating Simpson-Visser black hole, which has an additional parameter (0 ≤ l/2M ≤ 1), apart from mass (M) and rotation parameter (a).

Gravitational Lensing of Gravitational Waves: Effect of microlens population in lensing galaxies [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
With increasing sensitivities of the current ground-based gravitational-wave (GW) detectors, the prospects of detecting a strongly lensed GW signal are going to be high in the coming years.

KiDS-1000 Cosmology: Multi-probe weak gravitational lensing and spectroscopic galaxy clustering constraints [PDF]

open access: yesAstronomy & Astrophysics, 2020
We present a joint cosmological analysis of weak gravitational lensing observations from the Kilo-Degree Survey (KiDS-1000), with redshift-space galaxy clustering observations from the Baryon Oscillation Spectroscopic Survey (BOSS) and galaxy-galaxy ...

Geometric Outlines of the Gravitational Lensing and Its Astronomic Applications

open access: yesUniverse, 2023
Gravitational lensing is a topic of great application value in the field of astronomy. The properties and research methods of gravitational lensing are closely related to the geometric and relativistic characteristics of the background universe.

Gravitational lensing by black holes in the 4D Einstein-Gauss-Bonnet gravity [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
Recently, a non-trivial 4D Einstein-Gauss-Bonnet (EGB) theory of gravity, by rescaling the GB coupling parameter as α/(D−4), was formulated in [1], which bypasses Lovelock's theorem and avoids Ostrogradsky instability.

Please Repeat: Strong Lensing of Gravitational Waves as a Probe of Compact Binary and Galaxy Populations [PDF]

open access: yesAstrophysical Journal, 2021
Strong gravitational lensing of gravitational wave sources offers a novel probe of both the lens galaxy and the binary source population. In particular, the strong lensing event rate and the time-delay distribution of multiply imaged gravitational-wave ...

Gravitational Lensing of Acoustic Charged Black Holes

open access: yesThe Astrophysical Journal, 2023
We study the gravitational lensing of acoustic charged black holes in strong and weak field limit approximations. For this purpose, we first numerically obtain the deflection limit coefficients and deflection angle in the strong field limit.
