Strong Lensing of Gravitational Waves as Seen by LISA [PDF]

Physical Review Letters, 2010
We discuss strong gravitational lensing of gravitational waves from merging of massive black hole binaries in the context of the LISA mission. Detection of multiple events would provide invaluable information on competing theories of gravity, evolution and formation of structures and, with complementary observations, constraints on H_0 and other ...

Gravitational lensing effects of black hole with conformally coupled scalar hair

European Physical Journal C: Particles and Fields, 2023
In this paper, we investigate the gravitational lensing effects in the weak and strong field limits of a static black hole with conformally coupled scalar field.

Searching for Strong Gravitational Lenses

Space Science Reviews
AbstractStrong gravitational lenses provide unique laboratories for cosmological and astrophysical investigations, but they must first be discovered – a task that can be met with significant contamination by other astrophysical objects and asterisms.

Strong-lensing of Gravitational Waves by Galaxy Clusters [PDF]

Proceedings of the International Astronomical Union, 2017
AbstractDiscovery of strongly-lensed gravitational wave (GW) sources will unveil binary compact objects at higher redshifts and lower intrinsic luminosities than is possible without lensing. Such systems will yield unprecedented constraints on the mass distribution in galaxy clusters, measurements of the polarization of GWs, tests of General Relativity,

Gravitational lensing of gravitational waves: wave nature and prospects for detection [PDF]

, 2019
We discuss the gravitational lensing of gravitational wave signals from coalescing binaries. We delineate the regime where wave effects are significant from the regime where geometric limit can be used. Further, we focus on the effect of micro-lensing and the combined effect of strong lensing and micro-lensing.

Time delay of photons coupled to Weyl tensor in a regular phantom black hole

European Physical Journal C: Particles and Fields, 2020
Time delay of the photons coupled to the Weyl tensor in a regular phantom black hole is investigated in both weak and strong deflection gravitational lensing. We find that the time delay in the weak deflection lensing strongly depends on the phantom hair

Possible Discrimination of Black Hole Origins from the Lensing Rate of DECIGO and B-DECIGO Sources

The Astrophysical Journal, 2023
In this paper, we forecast the expected detection rates and redshift distributions of gravitationally lensed gravitational waves (GWs) from three different mass distributions of primordial black holes (PBHs) and two stellar formation models of ...

Strong field gravitational lensing in scalar tensor theories

, 2006
Strong field gravitational lensing in the Brans-Dicke theory has been studied. The deflection angle for photons passing very close to the photon sphere is estimated for the static spherically symmetric space-time of the theory and the position and ...

Constraining the Rastall parameters in static space–times with galaxy-scale strong gravitational lensing [PDF]

Monthly notices of the Royal Astronomical Society, 2019
Recently, Rastall gravity has undergone a significant surge in popularity. We obtain a power-law total mass-density profile for the inner region (within several effective radius) of early-type galaxies (ETGs) from the space-time structures which are ...

COOL-LAMPS. Discovery of COOL J0335−1927, a Gravitationally Lensed Quasar at z = 3.27 with an Image Separation of 23.″3

The Astrophysical Journal Letters, 2023
We report the discovery of COOL J0335−1927, a quasar at z = 3.27 lensed into three images with a maximum separation of 23.″3 by a galaxy cluster at z = 0.4178. To date, this is the highest redshift wide-separation lensed quasar known.
