The evolution of high-z proto-star clusters into local globular clusters
A. Della Croce, E. Vesperini, R. Pascale +4
The James Webb Space Telescope (JWST) detected numerous massive and relatively compact stellar clumps around proto-galaxies at high redshift (z>0.5). Their properties suggest that…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE) XX. Star formation in the tidal tail of NGC 4254
A. Boselli, A. Lupi, P. Serra +26
ALMA 12CO(1-0) observations of 42 star-forming regions located outside the disc of the Virgo Cluster galaxy NGC4254 within an HI gas tail produced during the galaxy's interaction w…
Bulge Fossil Fragments as a new population of factories of gravitational wave sources in the Galaxy
F. R. Ferraro, E. Vesperini, B. Lanzoni +9
The discovery of the complex stellar populations hosted in two massive stellar systems in the Galactic bulge, namely Terzan5 and Liller 1, posed intriguing questions about their or…
Type Ia supernova feedback effects on globular clusters of different masses
E. Lacchin, M. Donati, F. Calura +3
Through 3D hydrodynamical simulations, we explore the impact of Type Ia supernova (SN) explosions on the star formation history and chemical properties of second-generation (SG) st…
Mass loss and dynamical friction on the Fornax dSph galaxy in the Milky Way potential
Pierfrancesco Di Cintio, Giuliano Iorio, Carlo Nipoti +1
We study the interplay between mass-loss and dynamical friction (DF) on the orbital decay of the Fornax dwarf spheroidal galaxy in the potential of the Milky Way (MW). Using a simp…
The dynamical evolution of the stellar clumps in the Sparkler galaxy
Eric Giunchi, Federico Marinacci, Carlo Nipoti +4
Recent JWST observations detected stellar clumps around the z=1.4 gravitationally lensed Sparkler galaxy (of stellar mass ), with ages and metallici…
