Viscous Dark Energy Accretion Activities : Sonic Speed, Angular Momentum and Mach Number Studies
Sandip Dutta, Promila Biswas, Ritabrata Biswas
In this present article, we study different accretion properties regarding viscous accretion of dark energy. Modified Chaplygin gas is chosen as the dark energy candidate. Viscosit…
Posing Constraints on the Free Parameters of a New Model of Dark Energy EoS : Responses Through Cosmological Behaviours
Promila Biswas, Parthajit Roy, Ritabrata Biswas
Since the late 1990's observations of type Ia Supernova, our universe is predicted to experience a late time cosmic acceleration. Theoretical support to this observation were inten…
Barboza-Alcaniz Equation of State Parametrization : Constraining the Parameters in Different Gravity Theories
Promila Biswas, Ritabrata Biswas
To justify the twenty years old distant Ia Supernova observations which revealed to us that our universe is experiencing a late time cosmic acceleration, propositions of existence…
Interacting Models of Generalised Chaplygin Gas and Modified Chaplygin Gas with Barotropic Fluid
Promila Biswas, Ritabrata Biswas
In this letter we consider two different models of our present universe. We choose the models which are consisting different sets of two seperate fluids. The first one of each set…
