Novel modulus stabilization mechanism in higher dimensional f(R) Gravity
Shafaq Gulzar Elahi, Soumya Samrat Mandal, Soumitra SenGupta
In this work, we obtain a new warped solution for a 5-dimensional gravity in an anti de-Sitter bulk. The higher curvature term in the gravity action is shown to modify the…
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 shadow of Sgr A* and M87*
Indrani Banerjee, Subhadip Sau, Soumitra SenGupta
With the recent release of the black hole image of Sgr A* alongside the earlier image of M87*, one can now really hope to acquire a better understanding of the gravitational physic…
Aspects of non-singular bounce in modified gravity theories
Indrani Banerjee, Tanmoy Paul, Soumitra SenGupta
Scenario of a bouncing universe is one of the most active area of research to arrive at singularity free cosmological models. Different proposals have been suggested to avoid the s…
Ekpyrotic bounce driven by Kalb-Ramond field
Tanmoy Paul, Soumitra SenGupta
We propose an ekpyrotic bounce scenario driven by a second rank antisymmetric Kalb-Ramond field, where the universe initially contracts through an ekpyrotic stage having a non-sing…
