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…
Compact Object Modeling in the Globular Cluster 47 Tucanae
Claire S. Ye, Kyle Kremer, Carl L. Rodriguez +5
The globular cluster 47~Tucanae (47~Tuc) is one of the most massive star clusters in the Milky Way and is exceptionally rich in exotic stellar populations. For several decades it h…
Dynamical Formation Channels for Fast Radio Bursts in Globular Clusters
Kyle Kremer, Anthony L. Piro, Dongzi Li
The repeating fast radio burst (FRB) localized to a globular cluster in M81 challenges our understanding of FRB models. In this Letter, we explore dynamical formation scenarios for…
The imprint of superradiance on hierarchical black hole mergers
Ethan Payne, Ling Sun, Kyle Kremer +2
Ultralight bosons are a proposed solution to outstanding problems in cosmology and particle physics: they provide a dark-matter candidate while potentially explaining the strong ch…
Implications of Eccentric Observations on Binary Black Hole Formation Channels
Michael Zevin, Isobel M. Romero-Shaw, Kyle Kremer +2
Orbital eccentricity is one of the most robust discriminators for distinguishing between dynamical and isolated formation scenarios of binary black hole mergers using gravitational…
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…
The Supersonic Project: SIGOs, a Proposed Progenitor to Globular Clusters, and their Connections to Gravitational Wave Anisotropies
William Lake, Smadar Naoz, Yeou S. Chiou +4
Supersonically Induced Gas Objects (SIGOs), are structures with little to no dark matter component predicted to exist in regions of the Universe with large relative velocities betw…
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…
The Observed Rate of Binary Black Hole Mergers can be Entirely Explained by Globular Clusters
Carl L. Rodriguez, Kyle Kremer, Sourav Chatterjee +5
Since the first signal in 2015, the gravitational-wave detections of merging binary black holes (BBHs) by the LIGO and Virgo collaborations (LVC) have completely transformed our un…
Intermediate-mass Black Holes from High Massive-star Binary Fractions in Young Star Clusters
Elena González, Kyle Kremer, Sourav Chatterjee +5
Black holes formed in dense star clusters, where dynamical interactions are frequent, may have fundamentally different properties than those formed through isolated stellar evoluti…
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…
