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

Geometric Outlines of the Gravitational Lensing and Its Astronomic Applications
Universe, 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.

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

Strong Gravitational Lensing of Gravitational Waves: A Review
Universe, 2023 The first successful detection of gravitational waves (GWs) opened up a new window to study a realm of the most violent phenomena in the universe, such as coalescences of binary black holes (BH–BH), binary neutron stars (NS–NS), and mixed (BH–NS) systems,

Gravitational Lensing of Acoustic Charged Black Holes
The 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.

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

Detecting and Characterizing Young Quasars. III. The Impact of Gravitational Lensing Magnification
The Astrophysical Journal, 2023 We test the impact of gravitational lensing on the lifetime estimates of seven high-redshift quasars at redshift z ≳ 6. The targeted quasars are identified by their small observed proximity zone sizes, which indicate extremely short quasar lifetimes ( t ...

Beyond the Detector Horizon: Forecasting Gravitational-Wave Strong Lensing [PDF]
Astrophysical Journal, 2021 When gravitational waves pass near massive astrophysical objects, they can be gravitationally lensed. The lensing can split them into multiple wave fronts, magnify them, or imprint beating patterns on the waves.
