Gravitational lensing of fast radio bursts: prospects for probing microlens populations in lensing galaxies
Ashish Kumar Meena, Prasenjit Saha
Gravitational lensing by a stellar microlens of mass forms two images separated by micro-arcseconds on the sky and has a time delay of seconds…
Interference patterns for simple lens models in wave-optics regime
Ashish Kumar Meena
This work studies interference patterns created by simple lens models (point mass, Chang-Refsdal, and binary lens) in the wave optics regime, primarily in the context of lensing of…
Image formation near hyperbolic umbilic in strong gravitational lensing
Ashish Kumar Meena, Jasjeet Singh Bagla
Hyperbolic umbilic (HU) is a point singularity of the gravitational lens equation, giving rise to a ring-shaped image formation made of four highly magnified images, off-centred fr…
What are the parities of photon-ring images near a black hole?
Ashish Kumar Meena, Prasenjit Saha
Light that grazes a black-hole event horizon can loop around one or more times before escaping again, resulting for distance observers in an infinite sequence of ever fainter and m…
Exploring the Impact of Microlensing on Gravitational Wave Signals: Biases, Population Characteristics, and Prospects for Detection
Anuj Mishra, Ashish Kumar Meena, Anupreeta More +1
In this study, we investigate the impact of microlensing on gravitational wave (GW) signals in the LIGOVirgo sensitivity band. Microlensing caused by an isolated point lens, wit…
Wave Effects in Double-Plane Lensing
Rahul Ramesh, Ashish Kumar Meena, J S Bagla
We discuss the wave optical effects in gravitational lens systems with two point mass lenses in two different lens planes. We identify and vary parameters (i.e., lens masses, relat…
Gravitational Lensing of Core Collapse Supernova Gravitational Wave Signals
Rahul Ramesh, Ashish Kumar Meena, J. S. Bagla
We discuss the prospects of gravitational lensing of gravitational waves (GWs) coming from core-collapse supernovae (CCSN). As the CCSN GW signal can only be detected from within o…
Gravitational Waves from merging binaries
Jahanvi, Ashish Kumar Meena, J. S. Bagla
We discuss gravitational waves from merging binaries using a Newtonian approach with some inputs from the Post-Newtonian formalism. We show that it is possible to understand the ke…
