Expanding the time domain of multiple populations: evidences of nitrogen variations in the ~1.5 Gyr old star cluster NGC 1783
M. Cadelano, E. Dalessandro, M. Salaris +5
We present the result of a detailed analysis of HST UV and optical deep images of the massive and young (~1.5 Gyr) stellar cluster NGC 1783 in the Large Magellanic Cloud. This syst…
The physics governing the upper truncation mass of the globular cluster mass function
Meghan E. Hughes, Joel L. Pfeffer, Nate Bastian +5
The mass function of globular cluster (GC) populations is a fundamental observable that encodes the physical conditions under which these massive stellar clusters formed and evolve…
A black hole detected in the young massive LMC cluster NGC 1850
S. Saracino, S. Kamann, M. G. Guarcello +8
We report the detection of a black hole (NGC 1850 BH1) in the 100 Myr-old massive cluster NGC~1850 in the Large Magellanic Cloud. It is in a binary system with a main-sequenc…
Star Cluster Ecology: Revisiting the Origin of Iron and Age Complex Clusters
Nate Bastian, Joel Pfeffer
Typical globular clusters (GCs - young and old) host stellar populations with little or no star-to-star variations in heavy elements (e.g., Ca, Fe) nor in age. Nuclear star cluster…
Exploring the role of binarity in the origin of the bimodal rotational velocity distribution in stellar clusters
S. Kamann, N. Bastian, C. Usher +2
Many young and intermediate age massive stellar clusters host bimodal distributions in the rotation rates of their stellar populations, with a dominant peak of rapidly rotating sta…
Globular clusters as tracers of the dark matter halo: insights from the E-MOSAICS simulations
Marta Reina-Campos, Sebastian Trujillo-Gomez, Alis J. Deason +5
Globular clusters (GCs) are bright objects that span a wide range of galactocentric distances, and are thus probes of the structure of dark matter (DM) haloes. In this work, we exp…
