Extreme-mass ratio inspirals in strong segregation regime -- to inspiral or to get ejected?
Karamveer Kaur, Hagai Perets
Extreme-mass ratio inspirals (EMRIs) of stellar-mass black holes (BHs) are among the main targets for upcoming low-frequency gravitational wave (GW) detectors such as the Laser Int…
Semi-Analytical Fokker Planck Models for Nuclear Star Clusters
Karamveer Kaur, Barak Rom, Re'em Sari
We study the dynamics of nuclear star clusters, the dense stellar environments surrounding massive black holes in the centers of galaxies. We consider angular momentum diffusion du…
Dynamics around supermassive black holes: Extreme mass-ratio inspirals as gravitational-wave sources
Barak Rom, Itai Linial, Karamveer Kaur +1
Supermassive black holes and their surrounding dense stellar environments nourish a variety of astrophysical phenomena. We focus on the distribution of stellar-mass black holes aro…
Elevated Rates of Tidal Disruption Events in Active Galactic Nuclei
Karamveer Kaur, Nicholas C. Stone
Advances in time domain astronomy have produced a growing population of flares from galactic nuclei, including both tidal disruption events (TDEs) and flares in active galactic nuc…
Magnetically Dominated Disks in Tidal Disruption Events and Quasi-Periodic Eruptions
Karamveer Kaur, Nicholas C. Stone, Shmuel Gilbaum
The classical radiation pressure instability has been a persistent theoretical feature of thin, radiatively efficient accretion disks with accretion rates 1 to 100 per cent of the…
Density Wakes due to Dynamical Friction in Cored Potentials
Karamveer Kaur, Nicholas C. Stone
Dynamical friction is often modeled with reasonable accuracy by the widely used Chandrasekhar formula. However, in some circumstances, Chandrasekhar's local and uniform approximati…
The observed mass distribution of Galactic black hole LMXBs is biased against massive black holes
Peter G. Jonker, Karamveer Kaur, Nicholas Stone +1
The discovery of gravitational wave radiation from merging black holes (BHs) also uncovered BHs with masses in the range of ~20-160 Msun. In contrast, the most massive Galactic ste…
Stalling of Globular Cluster Orbits in Dwarf Galaxies
Karamveer Kaur, S. Sridhar
We apply the Tremaine-Weinberg theory of dynamical friction to compute the orbital decay of a globular cluster (GC), on an initially circular orbit inside a cored spherical galaxy…
Secular Instabilities of Keplerian Stellar Discs
Karamveer Kaur, Mher Kazandjian, S. Sridhar +1
We present idealized models of a razor-thin, axisymmetric, Keplerian stellar disc around a massive black hole, and study non-axisymmetric secular instabilities in the absence of ei…
Deformation of the Galactic Centre stellar cusp due to the gravity of a growing gas disc
Karamveer Kaur, S. Sridhar
The nuclear star cluster surrounding the massive black hole at the Galactic Centre consists of young and old stars, with most of the stellar mass in an extended, cuspy distribution…
