Strong Gravitational Lensing and Microlensing of Supernovae. [PDF]
Space Sci Rev, 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 ...

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.

Time-Delay Cosmography: Measuring the Hubble Constant and Other Cosmological Parameters with Strong Gravitational Lensing. [PDF]
Space Sci Rev, 2022 Multiply lensed images of a same source experience a relative time delay in the arrival of photons due to the path length difference and the different gravitational potentials the photons travel through.

On the detection and precise localisation of merging black holes events through strong gravitational lensing [PDF]
, 2022 To unlock the full spectrum of astrophysical and cosmological applications of gravitational-wave detections, it is essential to localise the associated black-hole mergers to high precision inside their host galaxies.

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.

Detecting low-mass haloes with strong gravitational lensing I: the effect of data quality and lensing configuration [PDF]
, 2022 This paper aims to quantify how the lowest halo mass that can be detected with galaxy-galaxy strong gravitational lensing depends on the quality of the observations and the characteristics of the observed lens systems.

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 .
