Effective Field Theory of Hairy Black Holes and Their flat/dS limit
Sayan Chakrabarti, Sumeet Chougule, Debaprasad Maity
Effective theory of fluctuations based on underlying symmetry plays very important role in understanding the low energy phenomena. Using this powerful technique we study the fluctu…
A note on electromagnetic and gravitational perturbations of the Bardeen de Sitter black hole: quasinormal modes and greybody factors
Sahel Dey, Sayan Chakrabarti
Bardeen de-Sitter (BdS) black hole is a spherically symmetric solution of Einstein's equation which is coupled to nonlinear electromagnetic field in a way that one gets a regular s…
Limitations of Pseudo-Newtonian approach in studying the accretion flow around Kerr black hole
Indu K. Dihingia, Santabrata Das, Debaprasad Maity +1
We study the relativistic accretion flow around a generic stationary axisymmetric space-time and obtain an effective potential () that accurately mimics the general re…
