From Density to Mass: A New Parametrized Framework for Dark Matter Environment Around Black Holes
Rajes Ghosh, Nicholas Speeney, Avijit Chowdhury +3
Astrophysical black holes (BHs) are not isolated vacuum objects but are expected to reside within complex environments, such as dark matter (DM) halos and baryonic distributions. S…
Accurate Black Hole Quasinormal Modes, Regge Poles, and Greybody Factors from Light Ring Ladder Symmetry
Rajes Ghosh, David Pereñiguez, Jaime Redondo-Yuste +1
The characteristic oscillations of a black hole can be understood in terms of null rays trapped near its unstable light ring, with this correspondence becoming exact in the high-fr…
How Universal Is the Black Hole Zeroth Law?
Rajes Ghosh, Sudipta Sarkar
The black hole zeroth law asserts the thermal equilibrium of a stationary Killing horizon, yet its status beyond general relativity remains limited. We demonstrate that its validit…
Universal Ladder Structure Across Scales: From Quantum to Black Hole Physics
Rajes Ghosh, Rajendra Prasad Bhatt, Sumanta Chakraborty +1
Second-order ordinary linear differential equations appear ubiquitously across physics, describing the behavior of systems from the quantum world of atoms to the classical world of…
