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…

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…

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…

FORECASTOR -- I. Finding Optics Requirements and Exposure times for the Cosmological Advanced Survey Telescope for Optical and UV Research mission

Isaac Cheng, Tyrone E. Woods, Patrick Côté +21

The Cosmological Advanced Survey Telescope for Optical and ultraviolet Research (CASTOR) is a proposed Canadian-led 1m-class space telescope that will carry out ultraviolet and blu…

Multimass modelling of Milky Way globular clusters -- II. present-day black hole populations

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

Populations of stellar-mass black holes (BHs) in globular clusters (GCs) influence their dynamical evolution and have important implications on one of the main formation channels f…

Multimass modelling of Milky Way globular clusters -- I. Implications on their stellar initial mass function above 1 M

Nolan Dickson, Vincent Hénault-Brunet, Holger Baumgardt +2

The distribution of stars and stellar remnants (white dwarfs, neutron stars, black holes) within globular clusters holds clues about their formation and long-term evolution, with i…

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…
