Linking globular cluster formation at low and high redshift through the age-metallicity relation in E-MOSAICS
Danny Horta, Meghan E. Hughes, Joel L. Pfeffer +4
We set out to compare the age-metallicity relation (AMR) of massive clusters from Magellanic Cloud mass galaxies in the E-MOSAICS suite of numerical cosmological simulations with a…
The Accreted Nuclear Clusters of the Milky Way
Joel Pfeffer, Carmela Lardo, Nate Bastian +2
A number of the massive clusters in the halo, bulge and disc of the Galaxy are not genuine globular clusters (GCs), but instead are different beasts altogether. They are the remnan…
Leveraging HST with MUSE: II. Na-abundance variations in intermediate age star clusters
S. Martocchia, S. Kamann, S. Saracino +13
Ancient (10 Gyr) globular clusters (GCs) show chemical abundance variations in the form of patterns among certain elements, e.g. N correlates with Na and anti-correlates with O.…
Leveraging HST with MUSE: I. Sodium abundance variations within the 2 Gyr-old cluster NGC 1978
S. Saracino, S. Kamann, C. Usher +10
Nearly all of the well studied ancient globular clusters (GCs), in the Milky Way and in nearby galaxies, show star-to-star variations in specific elements (e.g., He, C, N, O, Na, A…
Weighing stars from birth to death: mass determination methods across the HRD
Aldo Serenelli, Achim Weiss, Conny Aerts +31
The mass of a star is the most fundamental parameter for its structure, evolution, and final fate. It is particularly important for any kind of stellar archaeology and characteriza…
Where did the globular clusters of the Milky Way form? Insights from the E-MOSAICS simulations
Benjamin W. Keller, J. M. Diederik Kruijssen, Joel Pfeffer +5
Globular clusters (GCs) are typically old, with most having formed at z >~ 2. This makes understanding their birth environments difficult, as they are typically too distant to obse…
