Strong Gravitational Lensing and Microlensing of Supernovae. [PDF]

Space Sci Rev, 2023
Strong gravitational lensing and microlensing of supernovae (SNe) are emerging as a new probe of cosmology and astrophysics in recent years. We provide an overview of this nascent research field, starting with a summary of the first discoveries of ...

Strong Gravitational Lensing of Gravitational Waves: A Review

Universe, 2023
The first successful detection of gravitational waves (GWs) opened up a new window to study a realm of the most violent phenomena in the universe, such as coalescences of binary black holes (BH–BH), binary neutron stars (NS–NS), and mixed (BH–NS) systems,

Strong gravitational lensing by wormholes [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
We study strong gravitational lensing by a class of static wormhole geometries. Analytical approaches to the same are developed, and the results differ substantially from strong lensing by black holes, first reported by Bozza.

Time-Delay Cosmography: Measuring the Hubble Constant and Other Cosmological Parameters with Strong Gravitational Lensing. [PDF]

Space Sci Rev, 2022
Multiply lensed images of a same source experience a relative time delay in the arrival of photons due to the path length difference and the different gravitational potentials the photons travel through.

Detecting strong gravitational lensing of gravitational waves with TianQin [PDF]

Physical Review D, 2023
When gravitational waves (GWs) pass by a massive object on its way to Earth, a strong gravitational lensing effect will happen. Thus, the GW signal will be amplified, deflected, and delayed in time.

Strong gravitational lensing’s ‘external shear’ is not shear [PDF]

Monthly Notices of the Royal Astronomical Society, 2023
The distribution of mass in galaxy-scale strong gravitational lenses is often modelled as an elliptical power law plus ‘external shear’, which notionally accounts for neighbouring galaxies and cosmic shear along our line of sight.

Strong Gravitational Lensing with SKA [PDF]

New Astronomy Reviews, 2004
The advent of new observational facilities in the last two decades has allowed the rapid discovery and high-resolution optical imaging of many strong lens systems from galaxy to cluster scales, as well as their spectroscopic follow-up.

Strong gravitational lensing of explosive transients [PDF]

Reports on Progress in Physics, 2019
Recent rapid progress in time domain surveys makes it possible to detect various types of explosive transients in the Universe in large numbers, some of which will be gravitationally lensed into multiple images. Although a large number of strongly lensed

Strong Gravitational Lensing by Sgr A* [PDF]

Classical and Quantum Gravity, 2010
In recent years, there has been increasing recognition of the potential of the galactic center as a probe of general relativity in the strong field. There is almost certainly a black hole at Sgr A* in the galactic center, and this would allow us the ...
