    Density Bounding in the H II Regions of Galactic Disks: Evidence and Consequences
    We present four lines of evidence leading to the conclusion that a notable fraction of the ionizing photon emission from the stars within H II regions in the...

    Density waves and star formation in grand-design spirals
    Context. H II regions in the arms of spiral galaxies are indicators of recent star-forming processes. They may have been caused by the passage of the density...

    Derivation of star formation histories through deep color-magnitude diagrams: the dependency on stellar evolution models.
    We review the state of the art of the derivation of star formation histories from color-magnitude diagrams reaching the oldest main sequence turnoffs. From the...

    Deriving the star formation histories of galaxies from spectra with simulation-based inference
    High-resolution galaxy spectra encode information about the stellar populations within galaxies. The properties of the stars, such as their ages, masses, and...
