The mass-metallicity relation as a ruler for galaxy evolution: insights from the James Webb Space Telescope
A. Pallottini, A. Ferrara, S. Gallerani +5
Galaxy evolution emerges from the balance between cosmic gas accretion, fueling star formation, and supernova (SN) feedback, regulating the metal enrichment. Hence, the stellar mas…
ACOSMOS: the dust mass function and dust mass density at
A. Traina, B. Magnelli, C. Gruppioni +7
Context. Although dust in galaxies represents only a few percent of the total baryonic mass, it plays a crucial role in the physical processes occurring in galaxies. Studying the d…
A hidden active galactic nucleus powering bright [O III] nebulae in a protocluster at revealed by JWST
M. Solimano, J. González-López, M. Aravena +48
Galaxy protoclusters are sites of rapid growth, with a high density of massive galaxies driving elevated rates of star formation and accretion onto supermassive black holes. Here,…

The ALPINE-ALMA [CII] Survey: Dust emission effective radius up to 3 kpc in the Early Universe
F. Pozzi, F. Calura, Q. D'Amato +24
Measurements of the size of dust continuum emission are an important tool for constraining the spatial extent of star formation and hence the build-up of stellar mass. Compact dust…
