Unscreening of f(R) gravity near the galactic center black hole: Testability through pericenter shift below S0-2's orbit
Debojit Paul, Sanjeev Kalita, Abhijit Talukdar
General Relativity (GR) has been tested extensively in the solar system and is being tested in the new environment of the Galactic Centre (GC) black hole where the dimensionless gr…
General relativistic limit of f(R) gravity in the horizon scale of black hole
Pranjali Bhattacharjee, Sanjeev Kalita, Debojit Paul +1
The environment of the Galactic Centre (GC) black hole, Sgr A* gives us new opportunities to test black hole physics and deviation from General Relativity. In this analytical study…
gravity in the solar system and cosmological scalarons
Debojit Paul, Sanjeev Kalita
Since last two decades gravity theory has been extensively used as a serious alternative of general relativity to mimic the effects of dark energy. The theory presents a Yuk…
Kerr-scalaron metric and astronomical consequences near the Galactic Center black hole
Debojit Paul, Pranjali Bhattacharjee, Sanjeev Kalita
Astronomical tests of spacetime metric and gravitation theory near the Galactic Center (GC) black hole, Sgr A* have gained momentum with the observations of compact stellar orbits…
