Fast Dynamical Modelling of Milky Way Globular Clusters -- II. Impacts of Black Hole Prescriptions

Nolan Dickson, Vincent Hénault-Brunet, Fotios Fronimos Pouliasis +3

The populations of stellar-mass black holes (BHs) in globular clusters (GCs) play a key role in their dynamical evolution, however the mechanisms surrounding their formation and re…

Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign

T. Shenar, J. Bodensteiner, M. Abdul-Masih +73

Massive stars at low metallicity (Z) play a central role in shaping the high-redshift Universe, yet their multiplicity remains poorly constrained. The Binarity at Low Metallicity (…

Fast Dynamical Modelling of Milky Way Globular Clusters -- I. Implications for Initial Cluster Densities

Nolan Dickson, Vincent Hénault-Brunet, Fotios Fronimos Pouliasis +2

We infer the initial conditions of Milky Way (MW) globular clusters (GCs) from present-day observations, through the coupling of recently updated rapid cluster evolution models wit…

cBHBd: A fast code for the evolution of tidally limited star clusters and their binary black hole mergers

Fotios Fronimos Pouliasis, Nolan Dickson, Daniel Marín Pina +3

The evolution of star clusters is driven by stellar mass loss, two-body relaxation, and evaporation in the Galactic tidal field. Fast modeling tools are crucial for exploring diver…

Binarity at LOw Metallicity (BLOeM): Bayesian inference of natal kicks from inert black hole binaries

R. Willcox, P. Marchant, A. Vigna-Gómez +15

Context. The emerging population of inert black hole binaries (BHBs) provides a unique opportunity to constrain black hole (BH) formation physics. These systems are composed of a s…

UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey

Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86

The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…

Probing populations of dark stellar remnants in the globular clusters 47 Tuc and Terzan 5 using pulsar timing

Peter J. Smith, Vincent Hénault-Brunet, Nolan Dickson +2

We present a new method to combine multimass equilibrium dynamical models and pulsar timing data to constrain the mass distribution and remnant populations of Milky Way globular cl…

Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC

T. Shenar, J. Bodensteiner, H. Sana +74

Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary p…

Evidence for a bottom-light initial mass function in massive star clusters

Holger Baumgardt, Vincent Henault-Brunet, Nolan Dickson +1

We have determined stellar mass functions of 120 Milky Way globular clusters and massive LMC/SMC star clusters based on a comparison of archival Hubble Space Telescope photometry w…
