    Chemical Fingerprinting and Chemical Analysis of Galactic Halo Substructure
    We present high-resolution spectroscopic measurements of the abundances of the α-like element titanium (Ti) and s-process elements yttrium (Y) and lanthanum (La...

    Chemical history of isolated dwarf galaxies of the Local Group - I. dSphs: Cetus and Tucana
    For the first time, we obtain chemical evolution models (CEMs) for Tucana and Cetus, two isolated dwarf spheroidal galaxies of the Local Group. The CEMs have...

    Chemical Properties of Star-Forming Dwarf Galaxies
    Recent studies of the near-infrared (NIR) properties of dwarf irregular galaxies (dIs) and blue compact dwarfs (BCDs) have provided improved estimates for the...

    Chemical Signature of Gas-rich disc-disc Mergers at high Redshift
    We performed numerical simulations of mergers between gas-rich disc galaxies, which result in the formation of late-type galaxies. Stars formed during 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...

    CHEX-MATE: A non-parametric deep learning technique to deproject and deconvolve galaxy cluster X-ray temperature profiles
    Temperature profiles of the hot galaxy cluster intracluster medium (ICM) have a complex non-linear structure that traditional parametric modelling may fail to...

    Chronos: A NIR spectroscopic galaxy survey to probe the most fundamental stages of galaxy evolution
    We propose a dedicated, ultra-deep spectroscopic survey in the near infrared (NIR), that will target a mass-limited sample of galaxies during two of the most...

    Circum-nuclear gas flows in NGC 4151.
    We report broad-band imaging observations which reveal a circum-nuclear gas ring in NGC 4151. The ring is delineated by two arc-like features probably resulting...
