On the Nitrogen variation in ~2 Gyr old massive star clusters in the Large Magellanic Cloud
S. Martocchia, C. Lardo, M. Rejkuba +8
We present ESO/VLT FORS2 low resolution spectroscopy of red giant branch stars in three massive, intermediate age ( Gyr) star clusters in the Large Magellanic Cloud.…
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…
Is Fornax 4 the nuclear star cluster of the Fornax dwarf spheroidal galaxy?
S. Martocchia, E. Dalessandro, M. Salaris +2
Fornax 4 is the most distinctive globular cluster in the Fornax dwarf spheroidal. Located close to the centre of the galaxy, more metal-rich and potentially younger than its four c…
Searching for globular cluster chemical anomalies on the main sequence of a young massive cluster
I. Cabrera-Ziri, J. S. Speagle, E. Dalessandro +9
The spectroscopic and photometric signals of the star-to-star abundance variations found in globular clusters seem to be correlated with global parameters like the cluster's metall…
Searching for Multiple Populations in the Integrated Light of the Young and Extremely Massive Clusters in the Merger Remnant NGC~7252
Nate Bastian, Carmela Lardo, Christopher Usher +8
Recent work has shown that the properties of multiple populations within massive stellar clusters (i.e., in the extent of their abundance variations as well as the fraction of star…
