Constraining nuclear parameters using Gravitational waves from f-mode Oscillations in Neutron Stars
Bikram Keshari Pradhan, Dhruv Pathak, Debarati Chatterjee
Gravitational waves (GW) emanating from unstable quasi-normal modes in Neutron Stars (NS) could be accessible with the improved sensitivity of the current GW detectors or with the…
R-modes as a New Probe of Dark Matter in Neutron Stars
Swarnim Shirke, Suprovo Ghosh, Debarati Chatterjee +2
In this work, we perform the first systematic investigation of effects of the presence of dark matter on -mode oscillations in neutron stars (NSs). Using a self-interacting dark…
Constraining the equation of state of hybrid stars using recent information from multidisciplinary physics
Swarnim Shirke, Suprovo Ghosh, Debarati Chatterjee
At the ultra-high densities existing in the core of neutron stars, it is expected that a phase transition from baryonic to deconfined quark matter may occur. Such a phase transitio…
Multi-physics constraints at different densities to probe nuclear symmetry energy in hyperonic neutron stars
Suprovo Ghosh, Bikram Keshari Pradhan, Debarati Chatterjee +1
The appearance of strangeness in the form of hyperons within the inner core of neutron stars is expected to affect its detectable properties such as its global structure or gravita…
General relativistic treatment of -mode oscillations of hyperonic stars
Bikram Keshari Pradhan, Debarati Chatterjee, Michael Lanoye +1
We present a systematic study of -mode oscillations in neutron stars containing hyperons, extending recent results obtained within the Cowling approximation to linearized Genera…
Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift During the LIGO-Virgo Run O3b
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1632
We search for gravitational-wave signals associated with gamma-ray bursts detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced L…
