Scalar quasinormal modes in emergent modified gravity
Martin Bojowald, Erick I. Duque, S. Shankaranarayanan
Emergent modified gravity is a post-Einsteinian gravitational theory where spacetime geometry is not fundamental but rather emerges from the gravitational degrees of freedom in a n…
Interacting dark sector from Horndeski theories and beyond: Mapping fields and fluids
Pulkit Bansal, Joseph P Johnson, S. Shankaranarayanan
In Cosmology, when dissipative effects are minimal, the energy content of the Universe can be effectively described as a sum of perfect fluids. Perfect fluid descriptions ensure th…
Generation of effective massive Spin-2 fields through spontaneous symmetry breaking of scalar field
Susobhan Mandal, S. Shankaranarayanan
General relativity and quantum field theory are the cornerstones of our understanding of physical processes, from subatomic to cosmic scales. While both theories work remarkably we…
Prospects for cosmological constraints using gravitational wave memory
Indranil Chakraborty, Susmita Jana, S. Shankaranarayanan
The ΛCDM model has long served as a robust and predictive framework for cosmology, successfully explaining a wide range of observations, including the accelerated expansion of the…
Dynamical 4-D Gauss-Bonnet action from matter-graviton interaction at one-loop
Susobhan Mandal, S. Shankaranarayanan
The occurrence of singularities at the centers of black holes suggests that general relativity (GR), although a highly successful model of gravity and cosmology, is inapplicable. T…
Transient electromagnetic sources can detect solitary black holes in Milky Way galaxy
Susmita Jana, Rituparno Goswami, S. Shankaranarayanan +1
The Milky Way galaxy is estimated to host up to a billion stellar-mass solitary black holes (BHs). The number and distribution of BH masses can provide crucial information about th…
