Decoding the Imprints of Energy-Momentum Squared Gravity in Neutron Stars with Machine Learning Analysis

Sayantan Ghosh, Premachand Mahapatra, Dipti Deb

Neutron stars (NSs) provide a unique laboratory for testing gravity in the strong-field regime and for searching for deviations from General Relativity (GR). In this work, we inves…

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)…

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…

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…

Photon Ring Dimming as a Signature of Photon-Axion Conversion in Janis-Newman-Winicour Naked Singularity

Ayush Hazarika, Premachand Mahapatra, Subhadip Sau

The possible existence of axions in the universe introduces the intriguing possibility of photon-axion conversion in strong magnetic fields, particularly near compact objects like…

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…
