    Delayed Star Formation in Isolated Dwarf galaxies: Hubble Space Telescope Star Formation History of the Aquarius Dwarf Irregular
    We have obtained deep images of the highly isolated (d = 1 Mpc) Aquarius dwarf irregular galaxy (DDO 210) with the Hubble Space Telescope Advanced Camera for...

    Density biases and temperature relations for DESIRED H II regions
    We present a first study based on the analysis of the DEep Spectra of Ionized REgions Data base (DESIRED). This is a compilation of 190 high signal-to-noise...

    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 distribution of the cosmological matter field
    The one-point probability distribution function (PDF) of the matter density field in the universe is a fundamental property that plays an essential role in...

    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...

    DESI mock challenge. Halo and galaxy catalogues with the bias assignment method
    Context. We present a novel approach to the construction of mock galaxy catalogues for large-scale structure analysis based on the distribution of dark matter...

    Detailed chemical composition of the globular cluster Sextans A GC-1 on the outskirts of the Local Group
    Context. The chemical composition of globular clusters (GCs) across the Local Group provides information on chemical abundance trends. Studying GCs in isolated...
