    Observational hints of radial migration in disc galaxies from CALIFA
    Context. According to numerical simulations, stars are not always kept at their birth galactocentric distances but they have a tendency to migrate. The...

    Observing and Reducing IFUs: INTEGRAL and PMAS—Properties of the Ionized Gas in HH 202
    The reduction of integral field spectroscopy (IFS) data requires several stages and many repetitive operations to convert raw data into, typically, a large...

    Observing the Stellar Halo of Andromeda in Cosmological Simulations: The AURIGA2PANDAS Pipeline
    We present a direct comparison of the Pan-Andromeda Archaeological Survey (PAndAS) observations of the stellar halo of M31 with the stellar halos of six...

    OCCASO - II. Physical parameters and Fe abundances of red clump stars in 18 open clusters
    Open clusters have long been used to study the chemodynamical evolution of the Galactic disc. This requires a homogeneously analysed sample covering a wide...

    OCCASO - III. Iron peak and α elements of 18 open clusters. Comparison with chemical evolution models and field stars
    The study of open-cluster chemical abundances provides insights on stellar nucleosynthesis processes and on Galactic chemo-dynamical evolution. In this paper we...

    OCCASO. V. Chemical-abundance trends with Galactocentric distance and age
    Context. Open clusters provide valuable information on stellar nucleosynthesis and the chemical evolution of the Galactic disk, as their age and distances can...

    Old Main-Sequence Turnoff Photometry in the Small Magellanic Cloud. II. Star Formation History and its Spatial Gradients
    We present a quantitative analysis of the star formation history (SFH) of 12 fields in the Small Magellanic Cloud (SMC) based on unprecedented deep [(B - R), R]...

    Old-Aged Primary Distance Indicators
    Old-aged stellar distance indicators are present in all Galactic structures (halo, bulge, disk) and in galaxies of all Hubble types and, thus, are immensely...

    On a New Method to Estimate the Distance, Reddening, and Metallicity of RR Lyrae Stars Using Optical/Near-infrared (B, V, I, J, H, K) Mean Magnitudes: ω Centauri as a First Test Case
    We developed a new approach to provide accurate estimates of the metal content, reddening, and true distance modulus of RR Lyrae stars (RRLs). The method is...
