Hawking Radiation in Gravity: Survival of lighter black holes
Mriganka Dutta, Panchajanya Dey, Banibrata Mukhopadhyay
Einstein's theory of general relativity (GR) has been remarkably successful in describing gravitational phenomena. However, several open questions in modern cosmology and astrophys…
Discovering the Dispersion of Gravitational Waves using Multi-Band Observation including Deci-Hertz: A Unique Probe to Cosmic Acceleration
Adith Praveen, Panchajanya Dey, Suvodip Mukherjee
The dispersion in the speed of gravitational waves is a novel way to test the general theory of relativity and understand whether the origin of cosmic acceleration is due to any al…
Faster rate of Hawking radiation in modified gravity constraining dark matter
Panchajanya Dey, Banibrata Mukhopadhyay
The exact theory of gravity in the strong field regime is still under debate. There are observations implying the need for modification to Einstein's gravity. On the other hand, th…
General Relativistic Hydrodynamic Simulations around Accreting Black Holes
Sudip K Garain, Pranayjit Dey
Strong gravity in the immediate vicinity of compact objects (e.g., black holes, neutron stars) necessitates inclusion of general relativistic effects. Traditionally, pseudo-Newtoni…
