Modeling Stellar Collisions in Galactic Nuclei Using Hydrodynamic Simulations and Machine Learning
Sanaea C. Rose, James C. Lombardi, Elena González Prieto +2
Nuclear star clusters represent some of the most extreme collisional environments in the Universe. A nuclear star cluster like that of the Milky Way harbors a supermassive black ho…
Beyond Hierarchical Mergers: Accretion-Driven Origins of Massive, Highly Spinning Black Holes in Dense Star Clusters
Fulya Kıroğlu, Kyle Kremer, Frederic A. Rasio
GW231123, the most massive binary black hole (BBH) merger detected by LIGO/Virgo/KAGRA, highlights the need to understand the origins of massive, high-spin stellar black holes (BHs…
Spin-Orbit Alignment in Merging Binary Black Holes Following Collisions with Massive Stars
Fulya Kıroğlu, James C. Lombardi, Kyle Kremer +2
Merging binary black holes (BBHs) formed dynamically in dense star clusters are expected to have uncorrelated spin--orbit orientations since they are assembled through many random…
Formation of Stripped Stars From Stellar Collisions in Galactic Nuclei
C. Gibson, F. Kıroğlu, J. C. Lombardi +7
Tidal disruption events (TDEs) are an important way to probe the properties of stellar populations surrounding supermassive black holes. Observed spectra of several TDEs, such as A…
