Red vs. Blue: How metallicity shapes black hole dynamics and mergers in dense star clusters

Saloni Agrawal, Kyle Kremer, Michael Zevin +6

Dense star clusters are a well-established environment for the formation of gravitational wave sources through dynamical interactions. Recent LIGO-Virgo-KAGRA (LVK) events such as…

The Contribution of Disrupted Dense Star Clusters to Gaia's Compact Object Binaries

Aryanna Schiebelbein-Zwack, Claire S. Ye, Marta Reina-Campos +3

We present the first model of the Milky Way's detectable compact object--luminous star binary population from disrupted dense star clusters. We bridge large-scale cosmological star…

Black hole mergers from dense star clusters with realistic binary populations

Christopher E. O'Connor, Kyle Kremer, Saloni Agrawal +5

We present a suite of 24 full-lifetime simulations of dense star clusters with the Cluster Monte Carlo (CMC) code, featuring updated input physics and a realistic distribution of i…

Inferring Globular Cluster Initial Mass Function from Stellar Streams

Claire S. Ye, Raymond G. Carlberg

The Gaia mission has provided precise astrometry and spectrophotometry for billions of stars in the Milky Way, enabling the identification and kinematic characterization of stellar…

Connecting Cores and Black Hole Dynamics Across Scales: From Globular Clusters to Massive Ellipticals

Kyle Kremer, Newlin C. Weatherford, Philip F. Hopkins +2

The centers of massive elliptical galaxies exhibit a wide range in density profiles, from central cusps to resolved cores with order kiloparsec sizes. The cored ellipticals have be…

The ejection and detectability of high- and hyper-velocity stars by compact object binaries in globular clusters

Fraser A. Evans, Steffani M. Grondin, Claire S. Ye +3

The dense cores of Milky Way globular clusters (GCs) play host to a variety of dynamical encounters between stellar objects, which can accelerate stars to velocities high enough to…

The dominant mechanism(s) for populating the outskirts of star clusters with neutron star binaries

Nathan W. C. Leigh, Claire S. Ye, Steffani M. Grondin +3

It has been argued that heavy binaries composed of neutron stars (NSs) and millisecond pulsars (MSPs) can end up in the outskirts of star clusters via an interaction with a massive…

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…

Modeling Dense Star Clusters in the Milky Way and Beyond with the Cluster Monte Carlo Code

Carl L. Rodriguez, Newlin C. Weatherford, Scott C. Coughlin +10

We describe the public release of the Cluster Monte Carlo Code (CMC) a parallel, star-by-star -body code for modeling dense star clusters. CMC treats collisional stellar dynamic…

White Dwarf Subsystems in Core-Collapsed Globular Clusters

Kyle Kremer, Nicholas Z. Rui, Newlin C. Weatherford +5

Numerical and observational evidence suggests that massive white dwarfs dominate the innermost regions of core-collapsed globular clusters by both number and total mass. Using NGC…

No Black Holes in NGC 6397

Nicholas Z. Rui, Newlin Weatherford, Kyle Kremer +5

Recently, \citet{vitral2021does} detected a central concentration of dark objects in the core-collapsed globular cluster NGC 6397, which could be interpreted as a subcluster of ste…

Matching Globular Cluster Models to Observations

Nicholas Z. Rui, Kyle Kremer, Newlin C. Weatherford +4

As ancient, gravitationally bound stellar populations, globular clusters are abundant, vibrant laboratories characterized by high frequencies of dynamical interactions coupled to c…

Black Hole Mergers from Star Clusters with Top-Heavy Initial Mass Functions

Newlin C. Weatherford, Giacomo Fragione, Kyle Kremer +4

Recent observations of globular clusters (GCs) provide evidence that the stellar initial mass function (IMF) may not be universal, suggesting specifically that the IMF grows increa…

Black Hole Mergers from Hierarchical Triples in Dense Star Clusters

Miguel A. S. Martinez, Giacomo Fragione, Kyle Kremer +8

Hierarchical triples are expected to be produced by the frequent binary-mediated interactions in the cores of globular clusters. In some of these triples, the tertiary companion ca…

Demographics of triple systems in dense star clusters

Giacomo Fragione, Miguel A. S. Martinez, Kyle Kremer +6

Depending on the stellar type, more than \% and of stars in the field have at least one and two stellar companions, respectively. Hierarchical systems can be a…

The Role of "Black Hole Burning" in the Evolution of Dense Star Clusters

Kyle Kremer, Claire S. Ye, Sourav Chatterjee +2

As self-gravitating systems, dense star clusters exhibit a natural diffusion of energy from their innermost to outermost regions, which leads to a slow and steady contraction of th…

How initial size governs core collapse in globular clusters

Kyle Kremer, Sourav Chatterjee, Claire S. Ye +2

Globular clusters (GCs) in the Milky Way exhibit a well-observed bimodal distribution in core radii separating the so-called "core-collapsed" and "non-core-collapsed" clusters. Her…
