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…

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…
