The Life and Science of Thanu Padmanabhan
Jasjeet Singh Bagla, Krishnakanta Bhattacharya, Sumanta Chakraborty +21
Thanu Padmanabhan was a renowned Indian theoretical physicist known for his research in general relativity, cosmology, and quantum gravity. In an extraordinary career spanning fort…
An exact model for evaporating primordial black holes in cosmological space-time
Semin Xavier, Alan Sunny, S. Shankaranarayanan
Primordial black holes (PBHs) in the mass range are considered as possible dark matter candidates as they are not subject to big-bang nucleosynthesis c…
Non-minimally coupled electromagnetic fields and observable implications for primordial black holes
Susmita Jana, S. Shankaranarayanan
General relativity (GR) postulates have been verified with high precision, yet our understanding of how gravity interacts with matter fields remains incomplete. Various modificatio…
Can we bypass no-go theorem for Ricci-inverse Gravity?
Indranil Das, Joseph P Johnson, S. Shankaranarayanan
Recently, Amendola et al. proposed a geometrical theory of gravity containing higher-order derivative terms. The authors introduced anticurvature scalar , which is the trace o…
Analytical computation of quasi-normal modes of slowly-rotating black-holes in dCS gravity
Manu Srivastava, Yanbei Chen, S. Shankaranarayanan
Using gravitational wave observations to search for deviations from general relativity in the strong-gravity regime has become an important research direction. Chern Simons (CS) gr…
Maximal momentum GUP leads to quadratic gravity
Vijay Nenmeli, S. Shankaranarayanan, Vasil Todorinov +1
Quantum theories of gravity predict interesting phenomenological features such as a minimum measurable length and maximum momentum. We use the Generalized Uncertainty Principle (GU…
