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…

Probing the Origin of Primordial Black Holes through Novel Gravitational Wave Spectrum

Indra Kumar Banerjee, Ujjal Kumar Dey

In this article we investigate the cumulative stochastic gravitational wave spectra as a tool to gain insight on the creation mechanism of primordial black holes. We consider gravi…

Rotating hairy black holes and thermodynamics from gravitational decoupling

Subhash Mahapatra, Indrani Banerjee

We study the method of extended gravitational decoupling in obtaining static black hole solutions satisfying Einstein's equations with a tensor vacuum. The source has quite generic…

Do shadows of Sgr A* and M87* indicate black holes with a magnetic monopole charge?

Indrani Banerjee, Subhadip Sau, Soumitra SenGupta

We study the prospect of Bardeen black holes in explaining the observed shadow of Sgr A* and M87*. Bardeen black holes are regular black holes endowed with a magnetic monopole char…

Hunting extra dimensions in the shadow of Sgr A*

Indrani Banerjee, Sumanta Chakraborty, Soumitra SenGupta

We show that the observed angular diameter of the shadow of the ultra compact object Sgr A*, favours the existence of an extra spatial dimension. This holds irrespective of the nat…

Signatures of regular black holes from the quasar continuum spectrum

Indrani Banerjee

Regular black holes arising in Einstein gravity coupled to non-linear electrodynamics are worth studying as they can circumvent the r = 0 curvature singularity arising in general r…
