Strong gravitational lensing by a strongly naked null singularity
Suvankar Paul
We study strong gravitational lensing in a static, spherically symmetric, naked singularity spacetime, without a photon sphere. The nature of the singularity is found to be lightli…

Constraining modified gravity from tidal phenomena in binary stars
Pritam Banerjee, Debojyoti Garain, Suvankar Paul +2
In beyond-Horndeski theories of gravity, the Vainshtein screening mechanism might only be partially effective inside stellar objects. This results in a modification of the pressure…
