A note on methods for computing the critical curve of Kerr-like black holes
Siddharth Kumar Sahoo, Indrani Banerjee
This study systematically compares Bardeen's, de Vries's, and Grenzebach et al.'s celestial coordinate definitions of the critical curve ("shadow") of Kerr-like black holes. We fin…
Investigating the interplay of the braneworld gravity and the plasma environment on the black hole shadow
Siddharth Kumar Sahoo, Indrani Banerjee
We investigate the shadow of a rotating braneworld black hole in dispersive plasma environments and assess the potential of the Event Horizon Telescope (EHT) observations to constr…
Deciphering signatures of Kerr-Sen black holes in presence of plasma from the Event Horizon Telescope data
Siddharth Kumar Sahoo, Indrani Banerjee
The present work explores the role of the dilaton charge and the plasma environment in explaining the observed images of M87* and Sgr A*. Dilaton charges are associated with…
Imprints of Einstein-Maxwell dilaton-axion gravity in the observed shadows of Sgr A* and M87*
Siddharth Kumar Sahoo, Neeraj Yadav, Indrani Banerjee
Einstein-Maxwell dilaton-axion (EMDA) gravity provides a simple framework to investigate the signatures of string theory. The axion and the dilaton fields arising in EMDA gravity h…
Quasar continuum spectrum disfavors black holes with a magnetic monopole charge
Indrani Banerjee, Vijay Shersingh Chawan, Bhaswati Mandal +2
Black holes carrying a magnetic monopole charge are a subject of interest for a long time. In this work we explore the possibility of an observational evidence of such black holes…
