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…
PTOLEMY's test of generalized neutrino interactions: unveiling challenges and constraints
Indra Kumar Banerjee, Ujjal Kumar Dey, Newton Nath +1
Unanswered questions surrounding neutrinos have motivated investigations into physics beyond the standard model (SM) of particle physics. In particular, generalized neutrino intera…
Neutrino Decoherence from Generalised Uncertainty
Indra Kumar Banerjee, Ujjal Kumar Dey
Quantum gravity models predict a minimal measurable length which gives rise to a modification in the uncertainty principle. One of the simplest manifestations of these generalised…
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…
