Dynamics in Nuclear Stellar Clusters: The Impact of Collisions and Disrupted Binaries

Barak Rom, Re'em Sari

The nuclear stellar clusters surrounding supermassive black holes (SMBHs) host millions of stars and stellar remnants. We study how stellar collisions and binary disruptions, along…

Red Giant Destruction by Stellar and Black Hole Collisions in Galactic Nuclei

Barak Rom, Eliot Quataert

We study the impact of collisions involving red giants (RGs) in the dense stellar environments of galactic nuclei. We analytically estimate when collisions with main-sequence stars…

Universal Waveforms for Extreme Mass-Ratio Inspiral

Ilan Strusberg, Barak Rom, Re'em Sari

We engage with the challenge of calculating the waveforms of gravitational waves emitted by spinless binary black hole merger in extreme mass-ratio limit. We model the stellar-mass…

Mass Segregation and Transient Formation in Nuclear Stellar Clusters

Barak Rom, Re'em Sari

Supermassive black holes at the centers of galaxies occasionally disrupt stars or consume stellar-mass black holes (BHs) that wander too close, producing observable electromagnetic…

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…

Formation of Merging Stellar-Mass Black Hole Binaries by Gravitational Wave Emission in Active Galactic Nucleus Disks

Barak Rom, Re'em Sari, Dong Lai

Many stellar-mass Black Holes (sBHs) are expected to orbit supermassive black holes at galactic centers. For galaxies with Active Galactic Nuclei (AGN), it is likely that the sBHs…

Energy Flux and Particle Flux in Steady-State Solutions of Nuclear Star Clusters

Barak Rom, Itai Linial, Re'em Sari

We examine the effects of two-body interactions in a nuclear star cluster surrounding a supermassive black hole. We evaluate the energy flux, analogously to the particle flux calcu…

Extreme Mass-Ratio Binary Black Hole Merger: Characteristics of the Test-Particle Limit

Barak Rom, Re'em Sari

We study binary black hole mergers in the extreme mass-ratio limit. We determine the energy, angular momentum, and linear momentum of the post-merger, remnant black hole. Unlike pr…
