Expanding the time domain of multiple populations: evidences of nitrogen variations in the ~1.5 Gyr old star cluster NGC 1783
M. Cadelano, E. Dalessandro, M. Salaris +5
We present the result of a detailed analysis of HST UV and optical deep images of the massive and young (~1.5 Gyr) stellar cluster NGC 1783 in the Large Magellanic Cloud. This syst…
A black hole detected in the young massive LMC cluster NGC 1850
S. Saracino, S. Kamann, M. G. Guarcello +8
We report the detection of a black hole (NGC 1850 BH1) in the 100 Myr-old massive cluster NGC~1850 in the Large Magellanic Cloud. It is in a binary system with a main-sequenc…
Exploring the role of binarity in the origin of the bimodal rotational velocity distribution in stellar clusters
S. Kamann, N. Bastian, C. Usher +2
Many young and intermediate age massive stellar clusters host bimodal distributions in the rotation rates of their stellar populations, with a dominant peak of rapidly rotating sta…
High-resolution extinction map in the direction of the strongly obscured bulge fossil fragment Liller 1
Cristina Pallanca, Francesco R. Ferraro, Barbara Lanzoni +12
We used optical images acquired with the Wide Field Camera of the Advanced Camera for Surveys onboard the Hubble Space Telescope and near-infrared data from GeMS/GSAOI to construct…
A new identity card for the bulge globular cluster NGC 6440 from resolved star counts
Cristina Pallanca, Barbara Lanzoni, Francesco R. Ferraro +7
We present a new identity card for the cluster NGC 6440 in the Galactic Bulge. We have used a combination of high-resolution Hubble Space Telescope images, wide-field ground-based…
First phase space portrait of a hierarchical stellar structure in the Milky Way
E. Dalessandro, A. L. Varri, M. Tiongco +10
We present the first detailed observational picture of a possible ongoing massive cluster hierarchical assembly in the Galactic disk as revealed by the analysis of the stellar full…
