The multi-age stellar populations of Terzan 5 as revealed by JWST
G. Zullo, C. Pallanca, F. R. Ferraro +10
The James Webb Space Telescope provides an exciting opportunity to investigate stellar systems located in heavily obscured regions like the Galactic bulge. Possibly, the most enigm…
Revealing the stellar population of the ultra-obscured Galactic globular cluster Glimpse-C02
M. Loriga, M. Cadelano, C. Pallanca +10
In this paper, we present the results of a detailed photometric analysis of Glimpse-C02, one of the most extincted globular clusters of the Milky Way. We built a deep color magnitu…
A candidate to the long sought optical counterpart to the Rapid Burster in the bulge fossil fragment Liller 1
Cristina Pallanca, Francesco R. Ferraro, Barbara Lanzoni +6
We report on the possible identification of the optical counterpart of the Rapid Burster MXB 1730-335 in the stellar system Liller 1. The identification was performed by taking adv…
The Bulge Cluster Origin (BulCO) survey at the ESO-VLT: probing the early history of the Milky Way assembling. Design and first results in Liller1
F. R. Ferraro, L. Chiappino, A. Bartolomei +14
We present the scientific goals and the very first results of the Bulge Cluster Origin (BulCO) survey. This survey has been specifically designed to perform an unprecedented chemic…
The star formation history of the first bulge fossil fragment candidate Terzan 5
Chiara Crociati, Michele Cignoni, Emanuele Dalessandro +6
Context. Terzan 5 and Liller 1 are the only bulge stellar clusters hosting multi-iron and multi-age stellar populations. They are therefore claimed to constitute a novel class of a…
