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,

Strong gravitational lensing by wormholes [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 We study strong gravitational lensing by a class of static wormhole geometries. Analytical approaches to the same are developed, and the results differ substantially from strong lensing by black holes, first reported by Bozza.

Strong Gravitational Lensing and Microlensing of Supernovae [PDF]
Space Science Reviews, 2023 Strong gravitational lensing and microlensing of supernovae (SNe) are emerging as a new probe of cosmology and astrophysics in recent years. We provide an overview of this nascent research field, starting with a summary of the first discoveries of ...

Detecting strong gravitational lensing of gravitational waves with TianQin [PDF]
Physical Review D, 2023 When gravitational waves (GWs) pass by a massive object on its way to Earth, a strong gravitational lensing effect will happen. Thus, the GW signal will be amplified, deflected, and delayed in time.

Strong gravitational lensing’s ‘external shear’ is not shear [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 The distribution of mass in galaxy-scale strong gravitational lenses is often modelled as an elliptical power law plus ‘external shear’, which notionally accounts for neighbouring galaxies and cosmic shear along our line of sight.

Gravitational lensing around Kehagias–Sfetsos compact objects surrounded by plasma
European Physical Journal C: Particles and Fields, 2019 We study the optical properties of the Kehagias–Sfetsos (KS) compact objects, characterized by the “Hořava” parameter $$\omega _{_{KS}}$$ ωKS , in the presence of plasma, considering its homogeneous or power-law density distribution.

Strong gravitational lensing by loop quantum gravity motivated rotating black holes and EHT observations [PDF]
The European Physical Journal C, 2023 We investigate gravitational lensing in the strong deflection regime by loop quantum gravity (LQG)-motivated rotating black hole (LMRBH) metrics with an additional parameter l besides mass M and rotation a .

Constraining a modified gravity theory in strong gravitational lensing and black hole shadow observations [PDF]
Physical Review D, 2022 We study the strong gravitational lensing effect around rotating black holes in different gravity theories. By calculating the deflection angle of strong gravitational lensing, we evaluate the lensing observables including the image position, separation ...

Testing Strong Gravitational Lensing Effects of Supermassive Compact Objects with Regular Spacetimes [PDF]
Astrophysical Journal, 2022 We compare and contrast gravitational lensing, in the strong field limit, by the photon sphere in spherically symmetric regular electrically charged (REC) black holes (0 < b ≤ b E ) and with those by corresponding REC no-horizon spacetimes (b > b E ...
