Line-of-Sight Acceleration-driven waveform corrections for unequal-mass compact binary coalescences
Mohd Asim Ansari, Avinash Tiwari, Sajad A. Bhat +2
A constant line-of-sight acceleration (LOSA) of the centre-of-mass of a quasi-circular compact binary coalescence (CBC) leads to modulations in the gravitational-wave (GW) waveform…
Line-of-sight Acceleration Driven Effects in Eccentric Compact Binary Coalescences
Mohd Asim Ansari, Avinash Tiwari, Sajad A. Bhat +2
The line-of-sight acceleration (LOSA) effect, imprinted in the gravitational wave (GW) signal of an inspiralling compact binary by an external gravitational potential, is one of th…
Identifying and characterizing extragalactic circum-CBC exoplanets with future gravitational-wave detectors
Avinash Tiwari, Aditya Vijaykumar, Shasvath J. Kapadia +1
Exoplanets are high-value targets for a variety of ground and space-based telescopes. All known exoplanets are Galactic, and a fraction of them orbit compact objects. In this work,…
Periodic line-of-sight velocity-driven modulations to gravitational waves emitted by compact binaries in Keplerian outer orbits
Avinash Tiwari, Shasvath J. Kapadia, Aditya Vijaykumar +1
The centre of mass (CoM) of compact binary coalescences (CBCs) occurring in the vicinity of a supermassive black hole, through interaction with an arbitrary third body (e.g., of st…
Coalescence Forensics: Weighing the Hosts of Hierarchical Binary Black Hole Mergers
Avinash Tiwari, Shasvath J. Kapadia
We present a novel framework to infer the mass of clusters that host hierarchical binary black hole (BBH) mergers detected with gravitational-waves (GWs), on a single event basis.…
Gravitational Wave Informed Inference of 21-cm Global Signal Parameters
Avinash Tiwari, Sajad A. Bhat, Tirthankar Roy Choudhury +3
Understanding how and when the first stars and galaxies formed remains one of the central challenges in modern cosmology. These structures emerged during the transition from the Da…
