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…

Open Cluster Study Using I:Membership and Cluster Properties

Anindya Ganguly, Prasanta K. Nayak, Sourav Chatterjee

Star clusters are interesting laboratories to study star formation, single and binary stellar evolution, and stellar dynamics. We have used the exquisite data from 's data re…

On the stability of solutions to random optimization problems under small perturbations

Sourav Chatterjee, Souvik Ray

Consider the Euclidean traveling salesman problem with random points on the plane. Suppose that one of the points is shifted to a new random location. This gives us a new optim…

The Role of High-mass Stellar Binaries in the Formation of High-mass Black Holes in Dense Star Clusters

Ambreesh Khurana, Sourav Chatterjee

Recent detections of gravitational waves from mergers of binary black holes (BBHs) with pre-merger source-frame individual masses in the so-called upper mass-gap, expected due to (…

A Vershik-Kerov theorem for wreath products

Sourav Chatterjee, Persi Diaconis

Let be the group of permutations of that permutes the first symbols arbitrarily, then the next symbols and so on through the last symbols…

Profiling stellar environments of gravitational wave sources

Avinash Tiwari, Aditya Vijaykumar, Shasvath J. Kapadia +2

Gravitational waves (GWs) have enabled direct detections of compact binary coalescences (CBCs). However, their poor sky localisation and the typical lack of observable electromagne…

Liouville Theory: An Introduction to Rigorous Approaches

Sourav Chatterjee, Edward Witten

In recent years, a surprisingly direct and simple rigorous understanding of quantum Liouville theory has developed. We aim here to make this material more accessible to physicists…

Outcomes of Sub-Neptune Collisions

Tuhin Ghosh, Sourav Chatterjee, James C. Lombardi

Observed high multiplicity planetary systems are often tightly packed. Numerical studies indicate that such systems are susceptible to dynamical instabilities. Dynamical instabilit…

Detecting Detached Black Hole binaries through Photometric Variability

Chirag Chawla, Sourav Chatterjee, Neev Shah +1

Understanding the connection between the properties of black holes (BHs) and their progenitors is interesting in many branches of astrophysics. Discovering BHs in detached orbits w…

Stellar Escape from Globular Clusters. II. Clusters May Eat Their Own Tails

Newlin C. Weatherford, Frederic A. Rasio, Sourav Chatterjee +3

We apply for the first time the Monte Carlo star cluster modeling method to study tidal tail and stellar stream formation from globular clusters, assuming a circular orbit in a smo…

Monte Carlo Simulations of Globular Cluster Evolution. VI. The Influence of an Intermediate Mass Black Hole

Stefan Umbreit, John M. Fregeau, Sourav Chatterjee +1

We present results of a series of Monte Carlo simulations investigating the imprint of a central intermediate-mass black hole (IMBH) on the structure of a globular cluster. We inve…

Dynamical Interactions of Planetary Systems in Dense Stellar Environments

John M. Fregeau, Sourav Chatterjee, Frederic A. Rasio

We study dynamical interactions of star--planet binaries with other single stars. We derive analytical cross sections for all possible outcomes, and confirm them with numerical sca…
