A new proposal for Galactic dark matter: Effect of f(T) gravity
Farook Rahaman, Ritabrata Biswas, Hafiza Ismat Fatima +1
It is still a challenging problem to the theoretical physicists to know the exact nature of the galactic dark matter which causes the galactic rotational velocity to be more or les…
Expanding Universe: Thermodynamical Aspects From Different Models
Sridip Pal, Ritabrata Biswas
The pivotal point of the paper is to discuss the behavior of temperature, pressure, energy density as a function of volume along with determination of caloric EoS from following tw…
Presence of Dark Energy and Dark Matter : Does Cosmic Acceleration signifies a Weak Gravitational collapse?
Prabir Rudra, Ritabrata Biswas, Ujjal Debnath
In this work the collapsing process of a spherically symmetric star, made of dust cloud, in the background of dark energy is studied for two different gravity theories separately,…
Nature of singularity formed by the gravitational collapse in Husain space-time with electromagnetic field and scalar field
Ujjal Debnath, Prabir Rudra, Ritabrata Biswas
In this work, we have investigated the outcome of gravitational collapse in Husain space-time in the presence of electro-magnetic and a scalar field with potential. In order to stu…
