Change of Density when Chaplygin gas is accreting upon a black hole
Ritabrata Biswas
In this work I study the density change along the accretion and wind branches when modified Chaplygin gas is taken to be the accreting fluid. I get a high wind density very near to…
Interacting Holographic Dark Energy Model as a Dynamical system and the Coincidence Problem
Ritabrata Biswas, Nairwita Mazumder, Subenoy Chakraborty
We examine the evolution of a holographic cosmological model with future event horizon as the infrared cut-off and dark matter and dark energy do not evolve independently there…
A Study of Phase Transition in Black Hole Thermodynamics
Ritabrata Biswas, Subenoy Chakraborty
This paper deals with five-dimensional black hole solutions in (a) Einstein-Maxwell-Gauss-Bonnet theory with a cosmological constant and (b)Einstein-Yang-Mills-Gauss-Bonnet theory…
Hawking radiation as tunnelling from the trapping horizon of a general non-static spherically symmetric space-time
Subenoy Chakraborty, Nairwita Mazumder, Ritabrata Biswas
Using tunnelling approach, Hawking radiation is derived for a general class of non-static spherically symmetric space time. The standard tunnelling rate formula is obtained using t…
