PSR J0614-3329: A NICER case for Strange Quark Stars
Swarnim Shirke, Rajesh Maiti, Debarati Chatterjee
Precise measurements of neutron star masses and radii by the NICER mission impose important constraints on the nuclear equation of state. The most recent NICER measurement of PSR J…
-mode oscillations of dark matter admixed neutron stars
Swarnim Shirke, Debarati Chatterjee, Prashanth Jaikumar
We investigate -mode oscillations in dark matter admixed neutron stars employing a relativistic mean field model to describe hadronic matter and a model for self-interacting fer…
A White Paper on The Multi-Messenger Science Landscape in India
Samsuzzaman Afroz, Sanjib Kumar Agarwalla, Dipankar Bhattacharya +35
The multi-messenger science using different observational windows to the Universe such as Gravitational Waves (GWs), Electromagnetic Waves (EMs), Cosmic Rays (CRs), and Neutrinos o…
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…
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…
, a Numerical Simulator of Pulse Profiles for Binary Accreting X-ray Pulsars I: Beam Geometries
Parisee S. Shirke, Swarnim S. Shirke
The paper presents model pulse profiles from binary accreting X-ray pulsars using high-resolution numerical simulations for pencil and fan emission beam geometries, each with two d…
Effects of Dark Matter on -mode oscillations of Neutron Stars
Swarnim Shirke, Bikram Keshari Pradhan, Debarati Chatterjee +2
The effect of dark matter (DM) on -mode oscillations in DM admixed neutron stars (NSs) is investigated in a comprehensive analysis with particular attention to the role of the n…
Prospects of identifying the presence of Strange Stars using Gravitational Waves from binary systems
Bikram Keshari Pradhan, Swarnim Shirke, Debarati Chatterjee
The existence of self-bound strange stars is a long-standing mystery in astrophysics. Future astrophysical data, even with improved precision, may not allow us to discriminate them…
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…
