The effect of triaxial galaxy shapes on the dynamics of triple supermassive black holes in a cosmological context
Navonil Saha, Margarita Sobolenko, Peter Berczik +2
The hierarchical nature of galaxy formation in the Lambda cold dark matter (CDM) cosmological framework model often leads to the presence of multiple supermassive black holes (…
Formation of a nuclear star cluster through the inspiral of globular clusters: A case study of the dwarf elliptical galaxy UGC 7346
Ismael Khan, Fazeel Mahmood Khan, Andrea V. Macciò +2
Nuclear star clusters (NSCs) are dense stellar environments located in the center of most galaxies. NSCs are thought to form through two primary methods; through the inspiral of gl…
The LISA Astrophysics MBHcatalogues Project: A comparison of predictions of simulated massive black hole binaries
David Izquierdo-Villalba, Melanie Habouzit, Matteo Bonetti +67
In the hierarchical paradigm of galaxy formation, central massive black holes (MBHs) are expected to coalesce after the merger of their host galaxies. One of the main goals of the…
JWST Observations of the Double Nucleus in NGC 4486B: Possible Evidence for a Recent Binary SMBH Merger and Recoil
Behzad Tahmasebzadeh, Monica Valluri, Shashank Dattathri +19
A recent study of the compact elliptical galaxy NGC 4486B using JWST-NIRSpec IFU kinematics confirmed a supermassive black hole (SMBH) of mass (~8% of…
Intermediate Mass Black Hole Binary Evolution in Nuclear Star Clusters: the effect of the stellar mass black hole population
Fazeel Mahmood Khan, Peter Berczik, Margarita Sobolenko +4
In this study, we investigate the dynamics of Intermediate-Mass Black Hole (IMBH) binaries within Nuclear Star Clusters (NSCs) that contain a population of stellar-mass black holes…
Handy Relation Between Binary Black Hole Merger Times and Host Galaxy Properties
Kelly Holley-Bockelmann, Fazeel Khan, Isaiah Williams +6
Over the past 15 years, the evidence has clearly demonstrated that massive black hole (MBH) binary merger timescales depend strongly on the structural and kinematic properties of t…
