Testing selectively enhanced QCD axions couplings as an explanation of the RX J1856.5-3754 hard X-ray excess
Charul Rathod, Madhukar Mishra, P. K Das
We explore the possibility of explaining hard X-ray data obtained from one of the Magnificent Seven (M7) neutron-stars (NSs) employing QCD axion-converted photons. The emission of…
Bayesian Constraints on Inverse-Tangent Inflation with Constant-EOS Reheating and a Dynamical Reheating Analysis
Mayur Abhisheki, Prasanta Kumar Das
We perform a Bayesian inference analysis of an inflationary model based on an inverse-tangent potential, incorporating reheating dynamics in both constant and dynamical equation-of…
First Constraints on the Ellipticities of Self-Interacting Fermionic Dark Matter Admixed Neutron Stars from Continuous Gravitational-Wave Searches
Premachand Mahapatra, Andrew L. Miller, Prasanta Kumar Das
We investigate continuous gravitational-wave (CW) emission from rapidly rotating, non-axisymmetric, isolated neutron stars admixed with self-interacting fermionic dark matter (DM)…
Reheating and Inflationary dynamics driven by an inverse tangent potential
Mayur Abhisheki, Prasanta Kumar Das
In this work, we study the early universe inflation and the post-inflation reheating era employing an inverse tangent potential of the form $V=V_0 \cdot[tan^{-1}(\frac{κϕ}{m_p})]^2…
Structural Properties of Magnetized Neutron Stars under f (R, T ) Gravity Framework
Charul Rathod, M. Mishra, Prasanta Kumar Das
The current work investigates the structural properties of neutron stars in the presence of a strong magnetic field within the framework of f(R,T) modified gravity, where the matte…
Revealing Dark Matter's Role in Neutron Stars Anisotropy: A Bayesian Approach Using Multi-messenger Observations
Xue-Zhi Liu, Premachand Mahapatra, Chun Huang +3
Dark matter (DM) continues to evade direct detection, but neutron stars (NSs) serve as natural laboratories where even a modest DM component can alter their structure. While many s…
Thermal Evolution of Magnetars under f(R, T) Gravity
Charul Rathod, M. Mishra, Prasanta Kumar Das +1
The present study explores the thermal evolution and emission properties of neutron stars within the framework of modified gravity by solving the coupled energy-balance a…
Implications of Fermionic Dark Matter Interactions on Anisotropic Neutron Stars
Premachand Mahapatra, Chiranjeeb Singha, Ayush Hazarika +1
The presence of Dark matter (DM) within a neutron star (NS) can substantially influence the macroscopic properties. It is commonly assumed that the pressure inside an NS is isotrop…
Impacts of {} gravity on neutron stars study within the relativistic mean-field model framework in light of GW170817, Pulsars and NICER data
Premachand Mahapatra, Prasanta Kumar Das
In this work, we investigate the neutron star structure in conservative gravity with , where denotes the matter--geometry coupling. The modified stellar…
