From Geometry to Observation: Gravitational Waves and the Raychaudhuri Equation
Sougata Bhunia, Anubhab Dutta, Debashis Gangopadhyay +1
Gravitational waves (GWs) are independent of any particular theory of gravity. The universality of this notion is highlighted by the Raychaudhuri equation (RE), which is independen…
Non-Affine Extensions of the Raychaudhuri Equation in the K-essence Framework
Samit Ganguly, Goutam Manna, Debashis Gangopadhyay +2
We present a new avenue of the Raychaudhuri Equation (RE) by introducing a non-affine parametrization within the k-essence framework. This modification accounts for non-geodesic fl…
A dynamical system analysis of bouncing cosmology with spatial curvature
Soumya Chakraborty, Sudip Mishra, Subenoy Chakraborty
The present work deals with a FLRW cosmological model with spatial curvature and minimally coupled scalar field as the matter content. The curvature term behaves as a perfect fluid…
Dynamical system analysis of quintessence dark energy model
Soumya Chakraborty, Sudip Mishra, Subenoy Chakraborty
Our work deals with the dynamical system analysis of quintessence dark energy scalar field model with exponential potential. A dynamical system analysis has been applied at the bac…
Interacting tachyon with varying mass dark matter
Goutam Mandal, Sudip Mishra, Abdulla Al Mamon +1
This paper presents an investigation of cosmological dynamics of tachyon fluid coupled to varyingmass dark matter particles in the background of spatially flat FLRW universe. The m…
Effects of particle creation rate in two-fluid interacting cosmologies
Trishit Banerjee, Goutam Mandal, Atreyee Biswas +1
In this work, a two-fluid interacting model in a flat FLRW universe has been studied considering particle creation mechanism with a particular form of particle creation rate $Γ=Γ_0…
A study of interacting scalar field model from the perspective of the dynamical systems theory
Goutam Mandal, Soumya Chakraborty, Sudip Mishra +1
In this work, considering the background dynamics of flat Friedmann-Lemaitre-Robertson-Walker(FLRW) model of the universe, we investigate a scalar field model as dark energy candid…
Anisotropic strange star with Tolman-Kuchowicz metric under gravity
Suparna Biswas, Dibyendu Shee, B. K. Guha +1
In the current article, we study anisotropic spherically symmetric strange star under the background of gravity using the metric potentials of Tolman-Kuchowicz type~\cite{…
Neutron star under homotopy perturbation method
Abdul Aziz, Saibal Ray, Farook Rahaman +1
We obtain a mass function solving the Tolman-Oppenheimer-Volkoff (TOV) equation for isotropic and spherically symmetric system via homotopy perturbation method (HPM). Using the mas…
Relativistic strange stars in Tolman-Kuchowicz spacetime
Suparna Biswas, Dibyendu Shee, Saibal Ray +2
In this article we propose a relativistic model of a static spherically symmetric anisotropic strange star with the help of Tolman-Kuchowicz (TK) metric potentials [Tolman, Phys. R…
Constraining values of bag constant for strange star candidates
Abdul Aziz, Saibal Ray, Farook Rahaman +2
We provide a strange star model under the framework of general relativity by using a general linear equation of state (EOS). The solution set thus obtained is employed on altogethe…
Exploring physical features of anisotropic strange stars beyond standard maximum mass limit in gravity
Debabrata Deb, Sergei V. Ketov, S. K. Maurya +3
We study a specific model of anisotropic strange stars in the modified -type gravity by deriving solutions to the modified Einstein field equations rep…
Solar system tests in constraining parameters of dyon black holes
Farook Rahaman, Sabiruddin Molla, Amna Ali +1
In the present letter we examine the possibility of constraining dyon black holes based on the available observational data at the scale of the Solar system. For this we consider t…
Strange stars in Krori-Barua space-time under f(R; T) gravity
Suparna Biswas, Shounak Ghosh, B. K. Guha +2
In the present work, we study about highly dense compact stars which are made of quarks, specially strange quarks, adopting the Krori-Barua (KB)~\cite{Krori1975} metric in the fram…
Irreversible Thermodynamics of the Universe: Constraints from Planck Data
Subhajit Saha, Atreyee Biswas, Subenoy Chakraborty
The present work deals with irreversible Universal thermodynamics. The homogenous and isotropic flat model of the universe is chosen as open thermodynamical system and non-equilibr…
Scenario of inflationary cosmology from the phenomenological models
Saibal Ray, P. C. Ray, Partha Pratim Ghosh +2
Choosing the three phenomenological models of the dynamical cosmological term , viz., , and where is the cosmic scale facto…
