    The chemical evolution of the dwarf spheroidal galaxy Sextans
    We present our analysis of the FLAMES dataset targeting the central 25' region of the Sextans dwarf spheroidal galaxy (dSph). This dataset is the third major...

    The Chemical Evolution of the Monoceros Ring/Galactic Anticenter Stellar Structure
    The origin of the Galactic Anticenter Stellar Structure (GASS) or "Monoceros Ring"—a low-latitude overdensity at the edge of the Galactic disk spanning at least...

    The Chemical Properties of Milky Way and M31 Globular Clusters. I. A Comparative Study
    A comparative analysis is performed between high-quality integrated spectral indices of 30 M31 globular clusters, 20 Milky Way globular clusters, and a sample...

    The Chemical Properties of Milky Way and M31 Globular Clusters. II. Stellar Population Model Predictions
    We derive ages, metallicities, and abundance ratios ([α/Fe]) from the integrated spectra of 23 globular clusters in M31 by employing multivariate fits to two...

    The chemistry of planetary nebulae and HII regions in the dwarf galaxies Sextans A and B from deep VLT spectra
    Spectroscopic observations obtained with the VLT of one planetary nebula (PN) in Sextans A and of five PNe in Sextans A and of several H ii regions in these two...

    The Chemistry of Planetary Nebulae in the Outer Regions of M31
    We present spectroscopy of nine planetary nebulae (PNe) in the outskirts of M31, all but one obtained with the 10.4 m GTC telescope. These sources extend our...

    The chemo-dynamical groups of Galactic globular clusters
    We introduce a multicomponent chemo-dynamical method for splitting the Galactic population of globular clusters (GCs) into three distinct constituents: bulge...

    The CIDA-UCM-Yale shallow survey for emission-line galaxies
    We present the CIDA-UCM-Yale (Centro de Investigaciones de Astronomía, Universidad Complutense de Madrid, and Yale University) Survey (CUYS) for Hα+[NII] 6549...

    The Circum-Galactic Environment of LINERs
    In this paper, we study the circumgalactic environment of LINER host galaxies, in a sample of 166 objects drawn from a Multifrequency Catalogue of LINERs by...
