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…
A cosmological framework for stellar collisions at high redshift in proto-globular clusters, nuclear star clusters, and Little Red Dots
Claire E. Williams, Smadar Naoz, Sanaea C. Rose +8
Observations and cosmological simulations indicate that the early Universe hosted numerous compact, high-density stellar systems, where close encounters and physical collisions bet…
IRS 9: The Case for a Dynamically-Ejected Star from the Galactic Center
Matthew Hosek, Tuan Do, Smadar Naoz +7
Measuring stellar motions at the Milky Way's Galactic center (GC) provides unique insight into the dynamical processes within galactic nuclei. We present proper motion measurements…
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 (…
The Interplay of Stellar Evolution and Collisions in Galactic Nuclei
Jaden S. Sidhu, Sanaea C. Rose, Frederic A. Rasio
Nuclear star clusters (NSCs) surrounding supermassive black holes (SMBHs) are among the densest stellar environments in the universe. In these environments, collisions can shape th…
Fast Radio Bursts from White Dwarf Binary Mergers: Isolated and Triple-Induced Channels
Cheyanne Shariat, Claire S. Ye, Smadar Naoz +1
The detection of fast radio bursts (FRBs) in both young and old stellar populations suggests multiple formation pathways, beyond just young magnetars from core-collapse supernovae.…
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…
On the Orbital Effects of Stellar Collisions in Galactic Nuclei: Tidal Disruption Events and Ejected Stars
Sanaea C. Rose, Brenna Mockler
Dense stellar clusters surround the supermassive black holes (SMBH) in galactic nuclei. Interactions within the cluster can alter the stellar orbits, occasionally driving a star in…
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…
Collisional Shaping of Nuclear Star Cluster Density Profiles
Sanaea C. Rose, Morgan MacLeod
A supermassive black hole (SMBH) surrounded by a dense, nuclear star cluster resides at the center of many galaxies. In this dense environment, high-velocity collisions frequently…
Tidal Disruption Events from the Combined Effects of Two-Body Relaxation and the Eccentric Kozai-Lidov Mechanism
Denyz Melchor, Brenna Mockler, Smadar Naoz +2
Tidal disruption events (TDEs) take place when a star ventures too close to a supermassive black hole (SMBH) and becomes ruptured. One of the leading proposed physical mechanisms o…
Stellar Collisions in the Galactic Center: Massive Stars, Collision Remnants, and Missing Red Giants
Sanaea C. Rose, Smadar Naoz, Re'em Sari +1
Like most galaxies, the Milky Way harbors a supermassive black hole (SMBH) at its center, surrounded by a nuclear star cluster. In this dense star cluster, direct collisions can oc…
Tidal disruption events from eccentric orbits and lessons learned from the noteworthy ASASSN-14ko
Chang Liu, Brenna Mockler, Enrico Ramirez-Ruiz +5
Stars grazing supermassive black holes (SMBHs) on bound orbits may survive tidal disruption, causing periodic flares. Inspired by the recent discovery of the periodic nuclear trans…
