Gravitational Collapse In Husain Space-time For Brans-Dicke Gravity Theory with Power-law Potential
Prabir Rudra, Ritabrata Biswas, Ujjal Debnath
The motive of this work is to study gravitational collapse in Husain space-time in Brans-Dicke gravity theory. Among many scalar-tensor theories of gravity, Brans-Dicke is the simp…
Gravitational Collapse With Dark Energy And Dark Matter In Hořava-Lifshitz Gravity
Prabir Rudra, Ujjal Debnath
In this work, the collapsing process of a spherically symmetric star, made of dust cloud, is studied in Hořava Lifshitz gravity in the background of Chaplygin gas dark energy. Two…
Observational Constraints of Modified Chaplygin Gas in RS II Brane
Chayan Ranjit, Prabir Rudra, Sujata Kundu
FRW universe in RS II braneworld model filled with a combination of dark matter and dark energy in the form of modified Chaplygin gas (MCG) is considered. It is known that the equa…
How effective is new variable modified Chaplygin gas to play the role of dark energy- A dynamical system analysis in RS II Brane model
Prabir Rudra, Chayan Ranjit, Sujata Kundu
Motivated by some previous works of Rudra et al we set to explore the background dynamics when dark energy in the form of New Variable Modified Chaplygin gas is coupled to dark mat…
Role Of Generalized Cosmic Chaplygin Gas In Accelerating Universe : A Field Theoretical Prescription
Prabir Rudra
In this paper we investigate the role played by dark energy in the form of Generalized cosmic Chaplygin gas in an accelerating universe described by FRW cosmology. We have tried to…
