Black holes in Einstein-Gauss-Bonnet gravity: dynamical and 4-dimensional novel stationary black hole
Bhramar Chatterjee
We consider black hole in Einstein-Gauss-Bonnet(EGB) gravity in a dynamical setup and also the stationary black hole in recently discovered\cite{Glavan} -dimensional novel Einst…
Estimation of temperature of cosmological apparent horizons: a new approach
Bhramar Chatterjee, Narayan Banerjee
We consider radiation from cosmological apparent horizon in Friedmann-Lemaitre-Robertson-Walker(FLRW) model in a double-null coordinate setting. As the spacetime is dynamic, there…
Hawking radiation from dynamical horizons
Ayan Chatterjee, Bhramar Chatterjee, Amit Ghosh
In completely local settings, we establish that a dynamically evolving black hole horizon can be assigned a Hawking temperature. Moreover, we calculate the Hawking flux and show th…
Near-extremal black holes
Bhramar Chatterjee, Amit Ghosh
We present a new formulation of deriving Hawking temperature for near-extremal black holes using distributions. In this paper the near-extremal Reissner-Nordstrom and Kerr black ho…
Regularizing tunnelling calculations of Hawking temperature
Bhramar Chatterjee, P. Mitra
Attempts to understand Hawking radiation as tunnelling across a black hole horizon require the consideration of singular integrals. Although Schwarzschild coordinates lead to the s…
Hawking temperature and higher order calculations
Bhramar Chatterjee, P. Mitra
Hawking radiation has recently been explained by using solutions of wave equations across black hole horizons in a WKB approximation. Higher order calculations using both usual and…
