    The shape of oxygen abundance profiles explored with MUSE: evidence for widespread deviations from single gradients
    We characterised the oxygen abundance radial distribution of a sample of 102 spiral galaxies observed with VLT/MUSE using the O3N2 calibrator. The high spatial...

    The shapes of spiral arms in the S<SUP>4</SUP>G survey and their connection with stellar bars
    Context. Spiral galaxies are very common in the local Universe, but their formation, evolution, and interplay with bars remain poorly understood after more than...
