    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...
