X-ray emission from hot gas and XRBs in the NGC 5846 galaxy
Published 2025-01-01“…X-ray imaging analysis revealed the presence of 90 discrete X-ray point sources, spectral study of which depicted that the majority of them are LMXBs with a neutron star accretor. Among 90, only one source exhibits an X-ray luminosity greater than 1039ergs−11{0}^{39}\hspace{0.33em}{\rm{erg}}\hspace{0.33em}{{\rm{s}}}^{-1}, exceeding the Eddington limit for a canonical mass of a neutron star and occupies a position in the hard region of the X-ray color–color plot. …”

Strangeness in Astrophysics
Published 2025-01-01“…In this contribution the role of strangeness in astrophysics is discussed and, more precisely, strange hadronic matter in the interior of neutron stars. A special attention is payed to certain phenomena involving strange hadronic matter, such as the hyperon puzzle, kaon condensation and the thermal behaviour of hyperons in neutron star mergers.…”

Measurement of p−𝚵− (p - 𝚵+) Correlation Function in Isobar and Au+Au Collisions at √sNN = 200 GeV with the STAR Detector
Published 2025-01-01“…Understanding the strong interactions between baryons, especially hyperon-nucleon (Y-N) interactions, is crucial for comprehending the equation-of-state (EoS) of the nuclear matter and inner structure of neutron star. In these proceedings, we present the measurements of p−Ξ− (p¯ - Ξ¯+) correlation functions with high statistics in Isobar (Ru+Ru, Zr+Zr) and Au+Au collisions at √sNN = 200 GeV by the STAR experiment. …”

On the structure of quasi-Keplerian accretion discs surrounding millisecond X-ray pulsars
Published 2020“…Results obtained reveal that PGF results into episodic torque reversals that contribute to spinning-up or spinning-down of a neutron star, mainly from the inner region. The possibility of a quasi-Keplerian disc is seen and these results can explain the observed spin variations in MSPs like SAX J1808.4-3658 and XTE J1814-338.…”

Kilonova/Macronova Emission from Compact Binary Mergers
Published 2016-01-01“…We review current understanding of kilonova/macronova emission from compact binary mergers (mergers of two neutron stars or a neutron star and a black hole). Kilonova/macronova is emission powered by radioactive decays of r-process nuclei and it is one of the most promising electromagnetic counterparts of gravitational wave sources. …”

Stability of compact stars in a uniform density background cloud
Published 2024-12-01“…Abstract We are discussing a scenario where a compact star (neutron star, NS) is embedded in a thin, uniform density background cloud (a remnant cloud after a supernova or a cloud generated from the late stages of a star e.g., a planetary nebula or asymptotic red giant phases) and its effect on the stability of the compact star. …”

Population of Merging Compact Binaries Inferred Using Gravitational Waves through GWTC-3
Published 2023-03-01“…The Gravitational-Wave Transient Catalog 3 (GWTC-3) contains signals consistent with three classes of binary mergers: binary black hole, binary neutron star, and neutron star–black hole mergers. We infer the binary neutron star merger rate to be between 10 and 1700 Gpc^{−3} yr^{−1} and the neutron star–black hole merger rate to be between 7.8 and 140 Gpc^{−3} yr^{−1}, assuming a constant rate density in the comoving frame and taking the union of 90% credible intervals for methods used in this work. …”
