    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...

    DES to HSC: Detecting low-surface-brightness galaxies in the Abell 194 cluster using transfer learning
    Context. Low-surface-brightness galaxies (LSBGs) are important for understanding galaxy evolution and cosmological models. Nevertheless, the physical properties...

    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...

    Detailed chemical evolution models of the Tucana dSph galaxy
    We use semi-analytical methods to obtain detailed chemical evolution models (CEMs) for the dwarf spheroidal (dSph) galaxy Tucana. Published star formation rates...

    Detailed Photometric Study of the Merging Group of Galaxies HCG 95
    Results from Hα + continuum and Johnson UBVI imaging for HCG 95 are presented in order to study the star formation history of the galaxies in the group. Based...
