A Non-Linear Type Equation of State and Cosmic Fluid Dynamics
Shouvik Sadhukhan, Alokananda Kar, Surajit Chattopadhyay
In this chapter we have introduced a special type of non-linear equation of state to discuss the cosmological evolution mechanism. The new equation of state is a four parameters mo…
Binary Interaction with Multiple Fluid Type Cosmology Under Modified Gravity Frame
Alokananda Kar, Shouvik Sadhukhan
In the present chapter, we have established multiple fluid cosmological models under interaction scenarios. the interaction model we have established is a binary type of interactio…
Multiple fluid theory of cosmic evolution and its thermodynamic analysis
Shouvik Sadhukhan, Alokananda Kar, Surajit Chattopadhyay
In this paper we have discussed the modified gravity and scalar field DE model specifically DBI essence model with the analysis of thermodynamics during cosmological evolution. We…
Buchdahl Spacetime with Compact Body Solution of Charged Fluid and Scalar Field Theory
Manuel Malaver de la Fuente, Rajan Iyer, Alokananda Kar +3
The present work contains a discussion on compact stellar body that is influenced by the effects electromagnetic fields. We have tried to discuss a solution of Einstein-Maxwell fie…
Reconstruction of DBI-essence dark energy with f(R) gravity and its effect on black hole and wormhole mass accretion
Alokananda Kar, Shouvik Sadhukhan, Ujjal Debnath
In this paper, we have used the reconstructed DBI-essence dark energy density to modify the mass accretions of black holes and wormholes. In general, the black hole mass accretion…
Ultra-high Energy Gamma-rays from Past Explosions in our Galaxy
Alokananda Kar, Nayantara Gupta
The discovery of the sources of ultra-high energy photons by High-Altitude Water Cerenkov Gamma ray Observatory and Large High Altitude Air Shower Observatory in our Galaxy has rev…
Energy conditions for Inhomogeneous EOS and its Thermodynamics analysis with the resolution on finite time future singularity problems
Alokananda Kar, Shouvik Sadhukhan, Surajit Chattopadhay
In this paper we study two different cases of inhomogeneous EOS of the form p_d = ω(t)ρ_d+w_1 f(H, t) . We derive the energy density of dark fluid and dark matter component for bot…
Thermodynamics and energy condition analysis for Van-Der-Waals EOS without viscous cosmology
Alokananda Kar, Shouvik Sadhukhan, Surajit Chattopadhyay
In this paper we have studied Van-Der-Waals fluid system with the generalized EOS as as discussed in the recent works of Kremer, G.M [1, 4], Vardiashvili, G [2], Jantsch, R.C [3],…
Thermodynamic analysis for Non-linear system (Van-der-Waals EOS) with viscous cosmology
Shouvik Sadhukhan, Alokananda Kar, Surajit Chattopadhyay
The following paper has been motivated from recent works of Kremer, G.M [1, 4], Vardiashvili, G [2], Jantsch, R.C [3], Capozziello, S [5] on Van-Der-Waals EOS cosmology. The main a…
Condensed body mass accretion with DBI-essence dark energy and its reconstruction with f(Q) gravity
Alokananda Kar, Shouvik Sadhukhan, Ujjal Debnath
We have studied the reconstruction formalism of the DBI-essence dark energy scalar field model with the help of non-metricity of gravity or f(Q) gravity. The critical analysis has…
