    Chemical tagging with APOGEE: discovery of a large population of N-rich stars in the inner Galaxy
    Formation of globular clusters (GCs), the Galactic bulge, or galaxy bulges in general is an important unsolved problem in Galactic astronomy. Homogeneous...

    Chemical trends in the Galactic halo from APOGEE data
    The galaxy formation process in the Λ cold dark matter scenario can be constrained from the analysis of stars in the Milky Way's halo system. We examine the...

    Chemistry in the dIrr galaxy Leo A
    We present chemical abundance determinations of two H II regions in the dwarf irregular (dIrr) galaxy Leo A from Gran Telescopio Canarias (GTC) Optical System...

    Chemoarchaeological downsizing in a hierarchical universe: impact of a top-heavy IGIMF
    We make use of a semi-analytical model of galaxy formation to investigate the origin of the observed correlation between [α/Fe] abundance ratios and stellar...

    Chromospheric polarimetry through multiline observations of the 850 nm spectral region III: Chromospheric jets driven by twisted magnetic fields
    We investigate the diagnostic potential of the spectral lines at 850 nm for understanding the magnetism of the lower atmosphere. For that purpose, we use a...

    Chromospheric polarimetry through multiline observations of the 850-nm spectral region - II. A magnetic flux tube scenario
    In this publication, we continue the work started in Quintero Noda et al., examining this time a numerical simulation of a magnetic flux tube concentration. Our...

    CHRONOSTAR - II. Kinematic age and substructure of the Scorpius-Centaurus OB2 association
    The nearest region of massive star formation - the Scorpius-Centaurus OB2 association (Sco-Cen) - is a local laboratory ideally suited to the study of a wide...

    Circumgalactic medium of quasars: C IV absorption systems
    We investigate the properties of circumgalactic gas in the halo of quasar (QSO) host galaxies from C IV absorption-line systems. We use the optical spectroscopy...

    Circumnuclear kinematics in NGC 5248: the origin of nuclear spiral arms
    We present for the first time a two-dimensional velocity field of the central region of the grand-design spiral galaxy NGC 5248, at 0.9-arcsec spatial...
