Integrated cosmological memory: A dark-siren method to probe dark energy
Indranil Chakraborty, Sayantan Ghosh, Susmita Jana +2
Gravitational-wave (GW) cosmology is currently bottlenecked by the scarcity of electromagnetic counterparts for bright sirens and the systematic uncertainties of galaxy catalogs fo…
Signatures of asymmetry: Gravitational wave memory and the parity violation
Indranil Chakraborty, Susmita Jana, S. Shankaranarayanan
Einstein's equivalence principle suggests a deep connection between matter and spacetime, prompting the question: if matter violates parity, must gravity? This letter explores the…
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…
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…
A test of Einstein's equivalence principle in future VLBI observations
Joseph P Johnson, Susmita Jana, S. Shankaranarayanan
We show that very-long-baseline-interferometry (VLBI) observations of supermassive black holes will allow us to test the fundamental principles of General Relativity (GR). GR is ba…
Electromagnetic memory in arbitrary curved space-times
Susmita Jana, S. Shankaranarayanan
The gravitational memory effect and its electromagnetic (EM) analog are potential probes in the strong gravity regime. In the literature, this effect is derived for static observer…
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…
