Euclid: Data Release 1 (DR1) -- Fornax-7, an ultra-faint companion to the Fornax dwarf spheroidal galaxy? A remote star cluster or dwarf satellite of the Fornax dSph
T. Saifollahi, A. Lançon, A. M. N. Ferguson +165
We report the discovery of an ultra-faint stellar system in the vicinity of the Fornax dwarf spheroidal (dSph) galaxy in Euclid DR1. This system, which we designate Fornax-7, is lo…
Euclid: The potential of slitless infrared spectroscopy: A z=5.4 quasar and new ultracool dwarfs
E. Bañados, V. Le Brun, S. Belladitta +226
We demonstrate the potential of Euclid's slitless spectroscopy to discover high-redshift (z>5) quasars and their main photometric contaminant, ultracool dwarfs. Sensitive infrared…
Linking Photometry and spectroscopy: profiling multiple populations in globular clusters
E. Dondoglio, A. F. Marino, A. P. Milone +14
Our understanding of multiple populations in globular clusters (GCs) largely comes from photometry and spectroscopy: appropriate photometric diagrams can disentangle first and seco…
New perspective on the multiple population phenomenon in Galactic globular clusters from a wide-field photometric survey
S. Jang, A. P. Milone, A. F. Marino +10
Wide-field photometry of Galactic globular clusters (GCs) has been investigated to overcome limitations from the small field of view of the Hubble Space Telescope in the study of m…
Exploring Simple-Population and Multiple-Population Globular Clusters in the Outer Galactic Halo using the Hubble Space Telescope
E. P. Lagioia, A. P. Milone, M. V. Legnardi +13
The pseudo two-color diagram, known as chromosome map (ChM), is a valuable tool for identifying globular clusters (GCs) that consist of single or multiple stellar populations (MPs)…
On the original composition of the gas forming first-generation stars in clusters: insights from HST and JWST
M. V. Legnardi, A. P. Milone, G. Cordoni +8
Globular cluster (GC) stars composed of pristine material (first-generation, 1G, stars) are not chemically homogeneous, as they exhibit extended sequences in the "Chromosome Map" (…
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…
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)…
The chemical compositions of multiple stellar populations in the globular cluster NGC 2808
M. Carlos, A. F. Marino, A. P. Milone +8
Pseudo two-colour diagrams or Chromosome maps (ChM) indicate that NGC 2808 host five different stellar populations. The existing ChMs have been derived by the Hubble Space Telescop…
Chromosome maps of Globular Clusters from wide-field ground-based photometry
S. Jang, A. P. Milone, M. V. Legnardi +10
Hubble Space Telescope (HST) photometry is providing an extensive analysis of globular clusters (GCs). In particular, the pseudo two-colour diagram dubbed 'chromosome map (ChM)' al…
Constraining the original composition of the gas forming first-generation stars in globular clusters
M. V. Legnardi, A. P. Milone, L. Armillotta +13
Disentangling distinct stellar populations along the red-giant branches (RGBs) of Globular Clusters (GCs) is possible by using the pseudo two-color diagram dubbed chromosome map (C…
Integrated photometry of multiple stellar populations in Globular Clusters
S. Jang, A. P. Milone, E. P. Lagioia +8
Evidence that the multiple populations (MPs) are common properties of globular clusters (GCs) is accumulated over the past decades from clusters in the Milky Way and in its satelli…
