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…
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 Populations outside the tidal radius of NGC1851 through Gaia DR3 XP Spectra
Giacomo Cordoni, Anna F. Marino, Antonino P. Milone +6
Ancient Galactic Globular Clusters (GCs) have long fascinated astronomers due to their intriguing multiple stellar populations characterized by variations in light-element abundanc…
Hubble Space Telescope survey of Magellanic Cloud star clusters. UV-dim stars in young clusters
A. P. Milone, G. Cordoni, A. F. Marino +11
Young and intermediate-age star clusters of both Magellanic Clouds exhibit complex color-magnitude diagrams. In addition to the extended main-sequence turn-offs (eMSTOs), commonly…
Differential reddening in the direction of 56 Galactic globular clusters
M. V. Legnardi, A. P. Milone, G. Cordoni +6
The presence of differential reddening in the direction of Galactic globular clusters (GCs) has proven to be a serious limitation in the traditional colour-magnitude diagram (CMD)…
