The Impact of High-Mass Clusters on the Binary Black Hole Merger Rate over Cosmic Time
Aidan Mai, Kyle Kremer, Fulya Kıroğlu
We present a cosmological calculation of the binary black hole merger rate from dense star clusters, using a () model grid spanning the…
Using Machine Learning to Model Stellar Collisions in our Galactic Center
Tristan C. Sand, Sanaea C. Rose, Elena González Prieto +8
Direct collisions in the inner pc of the Galactic center can alter the orbits and properties of stars. The outcome of a collision depends on a number of parameters, including the m…
Explaining the X-ray Precursor, Ultra-long Prompt Emission, and Week-long Decay of GRB250702B with a Jetted Micro-TDE
Fulya Kıroğlu, Taeho Ryu, Alexander Tchekhovskoy +3
The longest detected gamma-ray burst, GRB250702B, exhibited seven hours of prompt -ray emission, preceded by a soft X-ray precursor ( day earlier) and followed by a weeks…
Machine Learning Methods for Stellar Collisions. I. Predicting Outcomes of SPH Simulations
Elena González Prieto, James C. Lombardi, Sanaea C. Rose +7
Stellar collisions can occur frequently in dense cluster environments, and play a crucial role in producing exotic phenomena from blue stragglers in globular clusters to high-energ…
Intermediate-Mass Black Hole Formation from Hierarchical Mergers in Galactic Nuclei
Amanda Newton, Sanaea C. Rose, Fulya Kıroğlu +2
Dense stellar environments like nuclear star clusters (NSCs) can dynamically assemble gravitational wave (GW) sources. We consider a population of single stellar mass black holes (…
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…
Shadows of the Colossus: Hierarchical Black Hole Mergers in a 10-million-body Globular Cluster Simulation
Aidan Mai, Kyle Kremer, Fulya Kıroğlu
The LIGO/Virgo/Kagra (LVK) Collaboration has detected numerous binary black hole mergers with properties that challenge standard binary evolution scenarios, such as component masse…
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…
Black Hole Accretion and Spin-up Through Stellar Collisions in Dense Star Clusters
Fulya Kıroğlu, Kyle Kremer, Sylvia Biscoveanu +2
Dynamical interactions in dense star clusters could significantly influence the properties of black holes, leaving imprints on their gravitational-wave signatures. While previous s…
Partial Tidal Disruption of Main-Sequence Stars by Intermediate-Mass Black Holes
Fulya Kıroğlu, James C. Lombardi, Kyle Kremer +3
We study close encounters of a middle-age main-sequence star (modeled using MESA) with massive black holes through hydrodynamic simulations, and explore in particula…
Formation of Low-mass Black Holes and Single Millisecond Pulsars in Globular Clusters
Kyle Kremer, Claire S. Ye, Fulya Kıroğlu +3
Close encounters between neutron stars and main-sequence stars occur in globular clusters and may lead to various outcomes. Here we study encounters resulting in tidal disruption o…
Gravitational Microlensing Rates in Milky Way Globular Clusters
Fulya Kıroğlu, Newlin C. Weatherford, Kyle Kremer +3
Many recent observational and theoretical studies suggest that globular clusters (GCs) host compact object populations large enough to play dominant roles in their overall dynamica…
