The role of mass loss in constraining quenching time in dwarf galaxies from AGB and RGB star counts
Paolo Ventura, Richard D'Souza, Flavia Dell'Agli +4
The capability of reconstructing the past star formation history of dwarf elliptical galaxies out of the Local Volume relies on modelling bright stellar populations currently evolv…
An analysis of the J-method from the perspective of the AGB evolution
C. Gavetti, P. Ventura, F. Dell'Agli +2
The JAGB method has been proposed as a distance indicator for Local Group galaxies. We investigate the populations of the J region in the (J-K,J) colour-magnitude plane of the Larg…
Dating N loud AGNs at high redshift: GS3073 as a snapshot of wCen like evolution of a nuclear star cluster
F. D'Antona, P. Ventura, A. F. Marino +8
In this paper we address two major questions raised by recent James Webb Space Telescope observations of the young Universe, namely: 1) what are the seed initial masses, and how ra…
FEAST: probing the stellar population of the starburst dwarf galaxy NGC4449 with JWST/NIRCam
Matteo Correnti, Giacomo Bortolini, Flavia Dell'Agli +22
We present new JWST/NIRCam observations of the starburst irregular galaxy NGC 4449, obtained in Cycle 1 as part of the Feedback in Emerging extrAgalactic Star clusTers (FEAST) prog…
A JWST project on 47 Tucanae. Binaries among multiple populations
A. P. Milone, A. F. Marino, M. Bernizzoni +25
Almost all globular clusters (GCs) contain multiple populations consisting of stars with varying helium and light-element abundances. These populations include first-population sta…
Mass loss along the red giant branch of the intermediate stellar populations in NGC6752 and NGC2808
M. Tailo, A. P. Milone, A. F. Marino +15
The morphology of the Horizontal Branch (HB) in Globular Clusters (GC) is among the early evidences that they contain multiple populations of stars. Indeed, the location of each st…
