    Arm and interarm abundance gradients in CALIFA spiral galaxies
    Spiral arms are the most singular features in disc galaxies. These structures can exhibit different patterns, namely grand design and flocculent arms, with...

    Arm-interarm gas abundance variations explored with MUSE: the role of spiral structure in the chemical enrichment of galaxies
    Spiral arms are the most characteristic features of disc galaxies, easily distinguishable due to their association with ongoing star formation. However, the...

    Arp 70: an interacting galaxy with extreme outflows
    We analysed a Fabry-Pérot (FP) cube of the interacting pair of galaxies Arp 70, which was obtained from the CeSAM public repository of FP data. On the larger...

    ARRAKIS: atlas of resonance rings as known in the S4G
    Context. Resonance rings and pseudorings (here collectively called rings) are thought to be related to the gathering of material near dynamical resonances...

    Assembly bias evidence in close galaxy pairs
    The growth channel of massive galaxies involving mergers can be studied via close pairs as putative merger progenitors, where the stellar populations of the...

    Astrometry and photometry of stars and star clusters in M33
    We present positions and magnitudes of stars and star clusters in a 1° × 1° area centered on M33. The survey is based on deep archival ground-based images using...
