Gravitational Lensing from a Spacetime Perspective [PDF]
Living Reviews in Relativity, 2004 The theory of gravitational lensing is reviewed from a spacetime perspective, without quasi-Newtonian approximations. More precisely, the review covers all aspects of gravitational lensing where light propagation is described in terms of lightlike ...

Gravitational Lensing of Continuous Gravitational Waves [PDF]
Universe, 2021 Continuous gravitational waves are analogous to monochromatic light and could therefore be used to detect wave effects such as interference or diffraction. This would be possible with strongly lensed gravitational waves.

The Scales of Gravitational Lensing
Universe, 2016 After exactly a century since the formulation of the general theory of relativity, the phenomenon of gravitational lensing is still an extremely powerful method for investigating in astrophysics and cosmology.

Geometric Outlines of the Gravitational Lensing and Its Astronomic Applications
Universe, 2023 Gravitational lensing is a topic of great application value in the field of astronomy. The properties and research methods of gravitational lensing are closely related to the geometric and relativistic characteristics of the background universe.

Gravitational Lensing of Acoustic Charged Black Holes
The Astrophysical Journal, 2023 We study the gravitational lensing of acoustic charged black holes in strong and weak field limit approximations. For this purpose, we first numerically obtain the deflection limit coefficients and deflection angle in the strong field limit.

Detecting and Characterizing Young Quasars. III. The Impact of Gravitational Lensing Magnification
The Astrophysical Journal, 2023 We test the impact of gravitational lensing on the lifetime estimates of seven high-redshift quasars at redshift z ≳ 6. The targeted quasars are identified by their small observed proximity zone sizes, which indicate extremely short quasar lifetimes ( t ...

Determination of Lens Mass Density Profile from Strongly Lensed Gravitational-wave Signals
The Astrophysical Journal, 2023 As the interferometers detecting gravitational waves are upgraded, improving their sensitivity, the probability of observing strong lensing increases. Once a detection is made, it will be critical to gain as much information as possible about the lensing

A Highly Magnified Gravitationally Lensed Red QSO at z = 2.5 with a Significant Flux Ratio Anomaly
The Astrophysical Journal, 2023 We present the discovery of a gravitationally lensed dust-reddened QSO at z = 2.517, identified in a survey for QSOs by infrared selection. Hubble Space Telescope imaging reveals a quadruply lensed system in a cusp configuration, with a maximum image ...

Gravitational Lensing of Supernova Neutrino Bursts
Universe, 2021 Supernova neutrino bursts have been observed from extragalactic distances. This note addresses the question of how gravitational lensing could distort the information in the burst.
