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…
Shape of U: Measuring the Curvature of the Universe with Gravitational Waves
Arindam Sharma, Ish Gupta, Anuradha Gupta
Gravitational waves (GWs) from compact binary mergers are standard sirens that can measure distances across the Universe without external calibrators. When an electromagnetic count…
Golden and Silver Dark Sirens for precise H0 measurement with HETDEX
Yixuan Dang, Ish Gupta, Robin Ciardullo +12
Gravitational waves (GWs) from compact binary coalescences are standard sirens that provide a direct measure of the source's luminosity distance, enabling an independent measuremen…
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 Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
The Critical Role of LIGO-India in the Era of Next-Generation Observatories
Shiksha Pandey, Ish Gupta, Koustav Chandra +1
We examine the role of LIGO-India in facilitating multi-messenger astronomy in the era of next generation observatories. A network with two L-shaped Cosmic Explorer (CE) detectors…
