Gaia EDR3 Parallax Distances to the Great Carina Nebula and Its Star Clusters (Trumpler 14, 15, 16)
Using offset-corrected Gaia EDR3 parallax measurements and spectrophotometric methods, we have determined distances for 69 massive stars in the Carina OB1 association and associated clusters:Expand
Modeling Dense Star Clusters in the Milky Way and Beyond with the Cluster Monte Carlo Code
We describe the public release of the Cluster Monte Carlo Code (CMC) a parallel, star-by-star N -body code for modeling dense star clusters. CMC treats collisional stellar dynamics using Hénon’sExpand
Probing dark matter with star clusters: a dark matter core in the ultra-faint dwarf Eridanus II
We present a new technique to probe the central dark matter (DM) density profile of galaxies that harnesses both the survival and observed properties of star clusters. As a first application, weExpand
Stellar-mass black holes in young massive and open stellar clusters and their role in gravitational-wave generation III: dissecting black hole dynamics
Stellar-remnant black holes (BH) in dense stellar clusters comprise a natural setup to trigger general-relativistic (GR) inspiral and merger of binary black holes (BBH), detectable by the LISA andExpand
If it does not kill them, it makes them stronger: collisional evolution of star clusters with tidal shocks
The radii of young (. 100 Myr) star clusters correlate only weakly with their masses. This shallow relation has been used to argue that impulsive tidal perturbations, or ‘shocks’, by passing giantExpand
A Measurement of Diffusion in 47 Tucanae
Using images from the Hubble Space Telescope Wide-Field Camera 3, we measure the rate of diffusion of stars through the core of the globular cluster 47 Tucanae using a sample of young white dwarfsExpand
When do stars in 47 Tucanae lose their mass
By examining the diffusion of young white dwarfs through the core of the globular cluster 47 Tucanae, we estimate the time when the progenitor star lost the bulk of its mass to become a white dwarf.Expand
Dust and gas in luminous proto-cluster galaxies at z=4.05: the case for different cosmic dust evolution in normal and starburst galaxies
We measure the dust and gas content of the three sub-millimeter galaxies (SMGs) in the GN20 proto-cluster at z=4.05 using new IRAM Plateau de Bure interferometer (PdBI) CO(4-3) and 1.2-3.3mmExpand
Extranuclear Hα-emitting complexes in low-z (U)LIRGs: precursors of tidal dwarf galaxies?
This paper characterizes the physical and kinematic properties of external massive star-forming regions in a sample of (U)LIRGs. We use high angular resolution ACS images from the Hubble SpaceExpand
Mass segregation and elongation of the starburst cluster Westerlund 1
Massive stellar clusters are the best available laboratories to study the mass function of stars. Based on NTT/SofI near-infrared photometry, we have investigated the properties of the massive youngExpand
