A novel inversion algorithm for weak gravitational lensing using quasi-conformal geometry
The challenge in weak gravitational lensing caused by galaxies and clusters is to infer the projected mass density distribution from gravitational lensing measurements, known as the inversion problem.

Diffraction around caustics in gravitational wave lensing
Gravitational lensing magnification is maximal around caustics. At these source locations, an incoming wave from a point source would formally experience an infinite amplification in the high-frequency or geometric optics limit.

Shadow and gravitational weak lensing around a quantum-corrected black hole surrounded by plasma
Chinese Physics C, High Energy Physics & Nuclear PhysicsIn this study, we investigate the optical properties of a quantum-corrected black hole (BH) in loop quantum gravity surrounded by a plasma medium. First, we determine the photon and shadow radii resulting from quantum corrections and the plasma medium in
