Open Astronomy, 2011 Multiple images of quasars formed by gravitational lensing are typically seen through the lensing galaxy. The granulation of the galaxy in stars or other compact objects induces local (‘microscopic’) but strong fluctuations in the gravitational potential

Reports on Progress in Physics, 1994 According to Einstein's general theory of relativity, a gravitational field bends electromagnetic waves in much the same way as low atmospheric air layers curve the trajectory of a propagating light ray. Large mass concentrations in the universe can thereby act as a type of lens, a gravitational lens.

The Astrophysical JournalThe recently discovered gravitational-wave event GW231123 is the most massive binary black hole merger detected to date. The inferred source masses of the event fall within the pair-instability supernova mass gap, where black holes formed directly from ...

Probing massive gravitons in f(R) with lensed gravitational waves
Physics Letters BWe investigate the novel features of gravitational wave solutions in f(R) gravity under proper gauge considerations in the shifted Ricci scalar background curvature (R1+ϵ).

Weak-lensing Approximation of Wave-optics Effects from General Symmetric Lens Profiles
The Astrophysical JournalGravitational lensing of electromagnetic (EM) waves has yielded many profound discoveries across fundamental physics, astronomy, astrophysics, and cosmology. Similar to EM waves, gravitational waves (GWs) can also be lensed.

Gravitational lensing derives its simplicity from some basic assumptions that are satisfied by most physical situations.The thin lens approximation and weak field approximations were used to build the whole theory and explain the phenomenology up to ...

Weak lensing and gravity theories
, 2005 We present the theory of weak gravitational lensing in cosmologies with generalized gravity, described in the Lagrangian by a generic function depending on the Ricci scalar and a non-minimally coupled scalar ...

A symplectic framework for multiplane gravitational lensing [PDF]
, 2002 We construct a new framework for the study of multiplane gravitational lensing from the view point of symplectic geometry. Symplectic relations are used to compose the systems and weaker Lagrangian equivalence is applied for classifying the caustics of ...
