GN-z11: witnessing the formation of second generation stars and an accreting massive black hole in a massive star cluster
F. D'Antona, E. Vesperini, F. Calura +7
We explore the possibility that the N-rich young proto-galaxy GN-z11 recently observed at z=10.6 by the James Webb Space Telescope is the result of the formation of second generati…
The metallicity variations along the chromosome maps: The Globular Cluster 47 Tucanae
A. F. Marino, A. P. Milone, E. Dondoglio +11
The "chromosome maps" (ChMs) of globular clusters (GCs) have revealed that these ancient structures are not homogeneous in metallicity in various ways, and in different natures. Th…
Photometric Binaries in 14 Magellanic Cloud Star Clusters
Anjana Mohandasan, Antonino P. Milone, Giacomo Cordoni +7
Binary stars play a major role in determining the dynamic evolution of star clusters. We used images collected with the Hubble Space Telescope to study fourteen Magellanic Clouds s…
A deep dive into the Type II Globular Cluster NGC 1851
E. Dondoglio, A. P. Milone, A. F. Marino +13
About one-fifth of the Galactic globular clusters (GCs), dubbed Type II GCs, host distinct stellar populations with different heavy elements abundances. NGC 1851 is one of the most…
Multiple stellar population mass loss in massive Galactic globular clusters
Elena Lacchin, Alessandra Mastrobuono-Battisti, Francesco Calura +4
The degree of mass loss, i.e. the fraction of stars lost by globular clusters, and specifically by their different populations, is still poorly understood. Many scenarios of the fo…
oMEGACat I: MUSE spectroscopy of 300,000 stars within the half-light radius of Centauri
M. S. Nitschai, N. Neumayer, C. Clontz +17
Omega Centauri ( Cen) is the most massive globular cluster of the Milky Way and has been the focus of many studies that reveal the complexity of its stellar populations and kine…
