Cosmography via stellar archaeology of low-redshift early-type galaxies from SDSS
Carlos A. Álvarez, Marcos M. Cueli, Alessandro Bressan +5
Cosmic chronometers offer a model-independent way to trace the expansion history of the Universe via the dating of passively evolving objects. This enables testing the validity of…
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…
Enhanced Mass Loss of Very Massive Stars: Impact on the Evolution, Binary Processes, and Remnant Mass Spectrum
Kendall G. Shepherd, Guglielmo Costa, Cristiano Ugolini +7
Very massive stars (VMS) play a fundamental role in astrophysics due to their winds and supernovae (SN), and their role as massive black hole (BH) progenitors. However, their origi…
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…
