Ages of the resolved stellar populations inside the JWST/MIRI bubbles in NGC 628

Avinash Ck, Divakara Mayya, Alessandro Bressan +3

JWST images in the MIRI filters are characterized by prominent interstellar bubbles, most of which are expected to be created by mechanical energy injected into the interstellar me…

Impact of initial mass function on the chemical evolution of high-redshift galaxies

Boyuan Liu, Michela Mapelli, Volker Bromm +10

Recent observations by the James Webb Space Telescope (JWST) have found evidence for an invariant relation between stellar mass, metallicity, and star formation rate up to $z\sim 8…

Strikingly high fraction of fast rotators in Magellanic Cloud star clusters

Greta Ettorre, Alessandro Mazzi, Leo Girardi +14

There has been growing evidence that the rich star clusters in the Magellanic Clouds contain significant fractions of rapidly rotating stars. In this work, we aim to constrain thes…

StAGE: Stellar Archaeology-driven Galaxy Evolution

Michele Bosi, Andrea Lapi, Lumen Boco +10

We build a semi-empirical framework of galaxy evolution (dubbed StAGE) firmly grounded on stellar archaeology. The latter provides data-driven prescriptions that, on a population s…

Spatially-resolved TRGB JWST color-magnitude as a tool to measure fossil stellar metallicity gradients in disk galaxies: NGC 628

Avinash CK, Y. Divakara Mayya, Alessandro Bressan +1

We use archival JWST/NIRCam images in the F115W, F150W, and F200W filters to measure the Tip of the Red Giant Branch (TRGB) magnitudes across the disk of the late-type spiral galax…

A new prescription for the spectral properties of population III stellar populations

Marie Lecroq, Stéphane Charlot, Alessandro Bressan +7

We investigated various emission properties of extremely low metallicity stellar populations in the Epoch of Reionization (EoR), using the new GALSEVN model, which has shown promis…

Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry

Gaia Collaboration, P. Panuzzo, T. Mazeh +412

Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…

GalaPy, the highly optimised C++/Python spectral modelling tool for galaxies -- I. Library presentation and photometric fitting

Tommaso Ronconi, Andrea Lapi, Martina Torsello +13

Fostered by upcoming data from new generation observational campaigns, we are about to enter a new era for the study of how galaxies form and evolve. The unprecedented quantity of…

The JWST Resolved Stellar Populations Early Release Science Program V. DOLPHOT Stellar Photometry for NIRCam and NIRISS

Daniel R. Weisz, Andrew E. Dolphin, Alessandro Savino +38

We present NIRCam and NIRISS modules for DOLPHOT, a widely-used crowded field stellar photometry package. We describe details of the modules including pixel masking, astrometric al…

Nebular emission from young stellar populations including binary stars

M. Lecroq, S. Charlot, A. Bressan +8

We investigate the nebular emission produced by young stellar populations using the new GALSEVN model based on the combination of the SEVN population-synthesis code including binar…

The impact of metallicity and dynamics on the evolution of young star clusters

M. Mapelli, A. A. Trani, A. Bressan

The early evolution of a dense young star cluster (YSC) depends on the intricate connection between stellar evolution and dynamical processes. Thus, N-body simulations of YSCs must…
