Orbital evolution of LIGO/Virgo binaries in stellar clusters driven by cluster tides, stellar encounters and general relativity
Alexander Rasskazov, Roman R. Rafikov
Origin of LIGO/Virgo gravitational wave events may involve production of binaries with relativistic components in dense stellar systems - globular or nuclear star clusters - and th…
Constraints on the Galactic Centre environment from \textit{Gaia} hypervelocity stars III: Insights on a possible companion to Sgr A*
Fraser A. Evans, Alexander Rasskazov, Amber Remmelzwaal +4
We consider a scenario in which Sgr A* is in a massive black hole binary (MBHB) with an as-of-yet undetected supermassive or intermediate-mass black hole companion. Dynamical encou…
On the eccentricity evolution of massive black hole binaries in stellar backgrounds
Matteo Bonetti, Alexander Rasskazov, Alberto Sesana +6
We study the dynamical evolution of eccentric massive black hole binaries (MBHBs) interacting with unbound stars by means of an extensive set of three body scattering experiments.…
Binary intermediate-mass black hole mergers in globular clusters
Alexander Rasskazov, Giacomo Fragione, Bence Kocsis
We consider the formation of binary intermediate black holes (BIMBH) in globular clusters (GC), which could happen either in situ or due to the mergers between clusters. We simulat…
The rate of stellar mass black hole scattering in galactic nuclei
Alexander Rasskazov, Bence Kocsis
We consider a black hole (BH) density cusp in a nuclear star cluster (NSC) hosting a supermassive back hole (SMBH) at its center. Assuming the stars and BHs inside the SMBH sphere…
Hypervelocity Stars from a Supermassive Black Hole-Intermediate-mass Black Hole binary
Alexander Rasskazov, Giacomo Fragione, Nathan W. C. Leigh +4
In this paper we consider a scenario where the currently observed hypervelocity stars in our Galaxy have been ejected from the Galactic center as a result of dynamical interactions…
The impact of stripped Nuclei on the Super-Massive Black Hole number density in the local Universe
Karina T. Voggel, Anil C. Seth, Holger Baumgardt +3
The recent discovery of super-massive black holes (SMBHs) in the centers of high-mass ultra compact dwarf galaxies (UCDs) suggests that at least some UCDs are the stripped nuclear…
The NANOGrav 11-year Data Set: Pulsar-timing Constraints On The Stochastic Gravitational-wave Background
Z. Arzoumanian, P. T. Baker, A. Brazier +57
We search for an isotropic stochastic gravitational-wave background (GWB) in the newly released -year dataset from the North American Nanohertz Observatory for Gravitational Wa…
Evolution Of Binary Supermassive Black Holes In Rotating Nuclei
Alexander Rasskazov, David Merritt
Interaction of a binary supermassive black hole with stars in a galactic nucleus can result in changes to all the elements of the binary's orbit, including the angles that define i…
Evolution Of Massive Black Hole Binaries In Rotating Stellar Nuclei: Implications For Gravitational Wave Detection
Alexander Rasskazov, David Merritt
We compute the isotropic gravitational wave (GW) background produced by binary supermassive black holes (SBHs) in galactic nuclei. In our model, massive binaries evolve at early ti…
