Beyond collective fluctuations: probing micro-image swarms in lensed quasars with intensity interferometry
Ashish Kumar Meena, Prasenjit Saha
Each strongly lensed image of a quasar behind a lensing galaxy (or galaxy cluster) is composed of a swarm of micro-images. This is a result of microlensing due to stellar-scale sub…
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…
Essentials of strong gravitational lensing
Prasenjit Saha, Dominique Sluse, Jenny Wagner +1
Of order one in 10^3 quasars and high-redshift galaxies appears in the sky as multiple images as a result of gravitational lensing by unrelated galaxies and clusters that happen to…
Microlensing of strongly lensed quasars
G. Vernardos, D. Sluse, D. Pooley +9
Strong gravitational lensing of quasars has the potential to unlock the poorly understood physics of these fascinating objects, as well as serve as a probe of the lensing mass dist…
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…
Strong Lensing by Galaxies
A. J. Shajib, G. Vernardos, T. E. Collett +7
Strong gravitational lensing at the galaxy scale is a valuable tool for various applications in astrophysics and cosmology. The primary uses of galaxy-scale lensing are to study el…
