Proceedings of 8th European VLBI Network Symposium — PoS(8thEVN), 2007 This is a short and biased review of gravitational lensing with emphasis on the radio and especially VLBI aspects. We briefly explain the basic idea and give a short sketch of the discovery of the first lens, before we more systematically discuss the general fields that can be studied with lensing.

Localizing merging black holes with sub-arcsecond precision using gravitational-wave lensing [PDF]
Monthly notices of the Royal Astronomical Society, 2020 The current gravitational-wave (GW) localization methods rely mainly on sources with electromagnetic counterparts. Unfortunately, a binary black hole does not emit light.

Aberration in gravitational lensing [PDF]
Physical Review D, 2008 It is known that a relative translational motion between the deflector and the observer affects gravitational lensing. In this paper, a lens equation is obtained to describe such effects on actual lensing observables. Results can be easily interpreted in terms of aberration of light-rays.

Probing the theory of gravity with gravitational lensing of gravitational waves and galaxy surveys [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The cross-correlation of gravitational wave strain with upcoming galaxy surveys probes theories of gravity in a new way. This method enables testing the theory of gravity by combining the effects from both gravitational lensing of gravitational waves ...

Identifying Strong Gravitational-wave Lensing during the Second Observing Run of Advanced LIGO and Advanced Virgo [PDF]
Astrophysical Journal, 2020 We perform Bayesian model selection with parameter estimation to identify potentially lensed gravitational-wave images from the second observing run (O2) of Advanced LIGO and Advanced Virgo.

Weak Gravitational Lensing [PDF]
Proceedings of Frontiers of Fundamental Physics 14 — PoS(FFP14), 2008 In this brief review I consider the advances made in weak gravitational lensing over the last 8 years, concentrating on the large scales - cosmic shear. I outline the theoretical developments, observational status, and the challenges which cosmic shear must overcome to realise its full potential. Finally I consider the prospects for probing Dark Energy

Strong gravitational lensing with SKA [PDF]
New Astronomy Reviews, 2004 Strong gravitational lenses provide an important tool to measure masses in the distant Universe, thus testing models for galaxy formation and dark matter; to investigate structure at the Epoch of Reionization; and to measure the Hubble constant and possibly w as a function of redshift.

Shadow and Weak Deflection Angle of a Black Hole in Nonlocal Gravity
Universe, 2022 Black hole shadow and gravitational lensing play important roles in testing gravitational theories in the strong field regime. As the first-order modifications from quantum gravity, the nonlocality can be manifested by black hole shadow and gravitational

Search for Gravitational Lensing Signatures in LIGO-Virgo Binary Black Hole Events [PDF]
Astrophysical Journal, 2019 We search for signatures of gravitational lensing in the binary black hole events detected by Advanced LIGO and Virgo during their first two observational runs.
