    Cleaning spectroscopic samples of stars in nearby dwarf galaxies. The use of the nIR Mg I line to weed out Milky Way contaminants
    Dwarf galaxies provide insight into the processes of star formation and chemical enrichment at the low end of the galaxy mass function, as well as into the...

    Clear detection of dusty torus signatures in a weak-line radio galaxy: the case of PKS 0043-42
    We report the clearest detection to date of dusty torus signatures in a weak-line radio galaxy (WLRG). The deep Spitzer InfraRed Spectrograph (IRS) rest-frame...

    Clear evidence for the early triggering of a luminous quasar-like active galactic nuclei in a major, gas-rich merger
    We present deep, intermediate resolution, long-slit Gemini GMOS-S optical spectra of the Sloan Digital Sky Survey (SDSS) type II quasar J002531-104022, which is...

    Clocking the assembly of double-barred galaxies with the MUSE TIMER project
    The formation of two stellar bars within a galaxy has proved challenging for numerical studies. It is not yet clear whether the inner bar is born via a star...

    Close Galaxy Counts as a Probe of Hierarchical Structure Formation
    The standard ΛCDM model predicts that the major merger rate of galaxy-size dark matter halos rises rapidly with redshift. The average number of close companions...

    Close-up view of a luminous star-forming galaxy at z = 2.95
    Exploiting the sensitivity of the IRAM NOrthern Extended Millimeter Array (NOEMA) and its ability to process large instantaneous bandwidths, we have studied the...

    Cloud-scale radio surveys of star formation and feedback in Triangulum Galaxy M 33: VLA observations
    Studying the interplay between massive star formation and the interstellar medium (ISM) is paramount to understand the evolution of galaxies. Radio continuum...

    CLOUDY modeling suggests a diversity of ionization mechanisms for diffuse extraplanar gas
    Context. The ionization of diffuse gas located far above the energetic midplane OB stars poses a challenge to the commonly accepted notion that radiation from...

    CLUES about M33: the reversed radial stellar age gradient in the outskirts of Triangulum galaxy
    HST/ACS observations along the major axis of M33 show that the mean age of its stars decreases with increasing distance from the galaxy centre. Such a behaviour...
