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…
