Strong Gravitational Lensing and Microlensing of Supernovae. [PDF]
Space Sci Rev, 2023 AbstractStrong 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 strongly lensed SNe. We describe the use of the time delays between multiple SN images as a way to

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.

Simulations of Strong Gravitational Lensing with Substructure [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 Galactic sized gravitational lenses are simulated by combining a cosmological N-body simulation and models for the baryonic component of the galaxy.

Strong gravitational lensing as a probe of dark matter [PDF]
arXiv, 2023 Dark matter structures within strong gravitational lens galaxies and along their line of sight leave a gravitational imprint on the multiple images of lensed sources. Strong gravitational lensing provides, therefore, a key test of different dark matter models in a way that is independent of the baryonic content of matter structures on subgalactic ...

Image Simulations for Strong and Weak Gravitational Lensing [PDF]
Symmetry, 2020 Gravitational lensing has been identified as a powerful tool to address fundamental problems in astrophysics at different scales, ranging from exoplanet identification to dark energy and dark matter characterization in cosmology.

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 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 ...

Strong gravitational lensing by multiple galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 We discuss strong gravitational lensing by multiple objects along any line of sight. The probability for strong gravitational lensing by more than one lens is small, but a number of strong lens systems in which more than one separate lens contribute significantly to the lensing potential will be detected in the large sample of lens systems compiled ...
