Relativistic Mean Field Approach with Chiral Symmetry Breaking and Quark Confinement in the light of Astrophysical Observations
Bikram Keshari Pradhan, Mohamad Chamseddine, Jérôme Margueron +4
We perform a Bayesian analysis of a relativistic mean-field approach, which is an implementation of the chiral confining model with both chiral symmetry breaking and confinement ef…
Astrometric Calibration of the 4-m International Liquid Mirror Telescope Observations
Vibhore Negi, Naveen Dukiya, Gokul Singh Mehra +12
The 4-m International Liquid Mirror Telescope (ILMT) is a dedicated time domain survey telescope that continuously scans the zenithal sky over the Indian Himalayas in the g', r' an…
NJL-Chiral Soliton and the Nucleon Equation of State at supra-saturation density: Impact of Chiral Symmetry Restoration
Bikram Keshari Pradhan, Guy Chanfray, Hubert Hansen +2
It has been conjectured that, at sufficiently high baryon densities, the equation of state (EoS) of bulk nuclear matter can be identified with that of the nucleon core. In this wor…
Fundamental oscillations as a tool to distinguish boson stars from neutron stars and black holes
Swarnim Shirke, Bikram Keshari Pradhan, Debarati Chatterjee +2
Massive boson stars are self-gravitating configurations of self-interacting scalar fields and can be modeled by a massive scalar field with a quartic self-interaction potential. It…
Detectability of Massive Boson Stars using Gravitational Waves from Fundamental Oscillations
Swarnim Shirke, Bikram Keshari Pradhan, Debarati Chatterjee +2
Boson Stars are macroscopic self-gravitating configurations made of complex scalar fields. These exotic compact objects would manifest as dark Boson stars and, in the absence of el…
Tidal heating in binary inspiral of strange quark stars
Suprovo Ghosh, José Luis Hernández, Bikram Keshari Pradhan +3
We investigate tidal heating associated with the binary inspiral of strange quark stars and its impact on the resulting gravitational wave signal. Tidal heating during the merger o…
