Distinguishing Kilonovae from Binary Neutron Star and Neutron Star-Black Hole Mergers
Ish Gupta, Yugesh Bhoge, Rahul Kashyap +1
Kilonovae (KNe) are most informative when accompanied by a gravitational-wave signal, which can help identify the source as a binary neutron star (BNS) or a neutron star-black hole…
Optimizing Bayesian model selection for equation of state of cold neutron stars
Rahul Kashyap, Ish Gupta, Arnab Dhani +2
We introduce a computational framework, Bayesian Evidence calculation fOr Model Selection (BEOMS) to evaluate multiple Bayesian model selection methods in the context of determinin…
The fine structure of the mean magnetic field in M31
Indrajit Paul, R. Vasanth Kashyap, Tuhin Ghosh +4
To explore the spatial variations of the regular (mean) magnetic field of the Andromeda galaxy (M31), we use Fourier analysis in azimuthal angle along four rings in the galaxy's pl…
Remnant properties of binary neutron star mergers undergoing prompt collapse
Arnab Dhani, Alessandro Camilletti, David Radice +4
We study the properties of remnants formed in prompt-collapse binary neutron star mergers. We consider non-spinning binaries over a range of total masses and mass ratios across a s…
Cosmic Calipers: Precise and Accurate Neutron Star Radius Measurements with Next-Generation Gravitational Wave Detectors
Sanika Khadkikar, Ish Gupta, Rahul Kashyap +3
Gravitational waves from merging binary neutron stars carry characteristic information about their astrophysical properties, including masses and tidal deformabilities, that are ne…
