Viability of Big Bang Nucleosynthesis in Gravity
Kajal Phukan, Rajdeep Mazumdar, Kalyan Malakar +1
We examine the viability of Big Bang Nucleosynthesis (BBN) constraints in gravity, where the gravitational Lagrangian is an arbitrary function of the the Ricci scalar $R…
Quantum-Corrected Thermodynamics and Phase Structure of AdS Euler-Heisenberg Black Hole
Siddhartha Sankar Borah, Dhruba Jyoti Gogoi, Kalyan Bhuyan
We investigate the thermodynamic behaviour of an AdS black hole arising from nonlinear electrodynamics-corrected gravity, incorporating quantum effects through thermal fluctuations…
Statistical insights on the decorrelation lengths of solar wind parameters at L1 point under varying conditions
Yogesh, Aparupa Apsara Baruah, Dibyendu Chakrabarty +3
Understanding the spatial coherence of solar wind plasma and magnetic field properties is essential for interpreting multi-spacecraft observations and for characterizing the large-…
Cosmological Realization of Baryon Asymmetry in f(R, G_{μν}T^{μν}) Gravity
Kalyan Malakar, Rajdeep Mazumdar, Kalyan Bhuyan
This work investigates the mechanism of gravitational baryogenesis (GB) under the formalism of f(R, G_{μν}T^{μν}) gravity, where R denotes the Ricci scalar, G_{μν} is the Einstein…
Astrophysical Signature and Optical Appearance of Weyl--Corrected Einstein--Maxwell Black Holes
Hassan Hassanabadi, Mrinnoy M. Gohain, Kalyan Bhuyan +1
In this work, we investigate the physics of charged black holes modified by Weyl corrections, which emerge from the non-minimal coupling between spacetime curvature and electromagn…
Exploring Rényi Entropic Cosmology Constrained by DESI DR2 BAO and Complementary Late-Time Observations
Rajdeep Mazumdar, Kalyan Malakar, Kalyan Bhuyan
We investigate the late-time cosmological viability of Rényi entropic cosmology (REC) by confronting its modified Friedmann dynamics with DESI DR2 BAO, cosmic chronometers, gravita…
Stability of the Einstein Static Universe in Zero-Point Length Cosmology with Topological Defects
Kalyan Bhuyan, Mrinnoy M. Gohain
Recently, zero-point length cosmology has shown some positive insights into some non-singular aspects of the early Universe. In addition, topological defects are known to play a si…
Cosmological Bounce Scenario with a Novel Parametrization of Bulk Viscosity
Rajdeep Mazumdar, Mrinnoy M. Gohain, Kalyan Bhuyan
In this work, we have studied how incorporating viscous fluids leads to exact bounce cosmological solutions in general relativity (GR) framework. Specifically, we propose a novel p…
Thermodynamics and Null Geodesics of a Schwarzschild Black Hole Surrounded by a Dehnen Type Dark Matter Halo
Mrinnoy M. Gohain, Prabwal Phukon, Kalyan Bhuyan
In this work, we derive a novel black hole solution surrounded by a Dehnen-(1,4,0) type dark matter halo by embedding a Schwarzschild black hole within the halo, constituting a com…
Emergent Cosmology in 4D Einstein Gauss Bonnet Theory of Gravity
Mrinnoy M. Gohain, Kalyan Bhuyan
In this paper, in an FLRW background and a perfect fluid equation of state, we explore the possibility of the realization of an emergent scenario in a 4D regularized extension of E…
Wormhole Formation with Gravitational Particle Creation Mechanism
Mrinnoy M. Gohain, Kalyan Bhuyan, Chayanika Chetia
We explore the possibility of formation of a traversable wormhole in General Relativity supported by particle creation mechanism. The repulsive back-reaction pressure generated thr…
