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…
The diverse outcomes of binary white dwarf mergers and connections to Galactic LISA sources
Kyle Kremer, Katelyn Breivik, Claire S. Ye
In the coming decade, the millihertz gravitational wave observatory LISA will provide the best constraints yet on the tens of thousands of close white dwarf binaries in the Milky W…
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.…
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…
Very Massive Stars and High N/O: A Tale of the Nitrogen-enriched Super Star Cluster in the Sunburst Arc
Yanlong Shi, Liang Dai, Norman Murray +3
The lensed Sunburst Arc () hosts a young (--), massive (), compact () Lyman-continuum (LyC) le…
Is GW231123 a hierarchical merger?
Lachlan Passenger, Sharan Banagiri, Eric Thrane +4
The binary black hole merger GW231123 is both the most massive gravitational-wave event observed and has the highest component spins measured to date. The dimensionless spins of th…
Mass Distribution of Binary Black Hole Mergers from Young and Old Dense Star Clusters
Claire S. Ye, Maya Fishbach, Kyle Kremer +1
Dense star clusters are thought to contribute significantly to the merger rates of stellar-mass binary black holes (BBHs) detected by the LIGO-Virgo-KAGRA collaboration. We combine…
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…
Gravitational-wave kicks impact spins of black holes from hierarchical mergers
Angela Borchers, Claire S. Ye, Maya Fishbach
One proposed black hole formation channel involves hierarchical mergers, where black holes form through repeated binary mergers. Previous studies have shown that such black holes f…
Binary properties of the globular cluster 47 Tuc (NGC 104). A dearth of short-period binaries
Johanna Müller-Horn, Fabian Göttgens, Stefan Dreizler +4
Spectroscopic observations of binary stars in globular clusters are essential to shed light on the poorly constrained period, eccentricity, and mass ratio distributions and to deve…
Predicting the rate of fast radio bursts in globular clusters from binary black hole observations
Aryamann Rao, Claire S. Ye, Maya Fishbach
The repeating fast radio burst (FRB) source in an old globular cluster (GC) in M81 proves that FRBs, which are typically associated with young magnetars, can also occur in old stel…
Can slow pulsars in Milky Way globular clusters form via partial recycling?
Kyle Kremer, Claire S. Ye, Craig O. Heinke +3
Alongside the population of several hundred radio millisecond pulsars currently known in Milky Way globular clusters, a subset of six slowly spinning pulsars (spin periods $0.3-4\,…
Investigating cannibalistic millisecond pulsar binaries using MESA: New constraints from pulsar spin and mass evolution
Devina Misra, Manuel Linares, Claire S. Ye
Compact binary millisecond pulsars (MSPs) with orbital periods d are key to understanding binary evolution involving massive neutron stars (NSs). Due to the ablation of…
Lower-mass-gap Black Holes in Dense Star Clusters
Claire S. Ye, Kyle Kremer, Scott M. Ransom +1
The existence of compact stellar remnants in the mass range has long been debated. This so-called lower mass gap was initially suggested by the lack of low-mass X-…

Claire S. Ye, Maya Fishbach
Gravitational-wave detectors are unveiling a population of binary black hole (BBH) mergers out to redshifts , and are starting to constrain how the BBH population evol…
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…
