    Chemical Evolution and the Galactic Habitable Zone of M31
    We have computed the Galactic Habitable Zones (GHZs) of the Andromeda galaxy (M31) based on the probability of terrestrial planet formation, which depends on...

    Chemical evolution of elliptical galaxies with a variable IMF. A publicly available code
    Growing evidence in recent years suggests a systematic variation of the stellar initial mass function (IMF), being top-heavy for starburst galaxies and possibly...
  • Publication
    Chemical evolution of ultra-faint dwarf galaxies in the self-consistently calculated integrated galactic IMF theory
    The galaxy-wide stellar initial mass function (gwIMF) of a galaxy in dependence on its metallicity and star formation rate can be calculated by the integrated...

    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...
  • Publication
    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...

    Chemo-dynamics of the stellar component of the Sculptor dwarf galaxy: I. Observed properties
    Aims. Recently, both the presence of multiple stellar chemo-kinematic components and rotation in the Sculptor dwarf spheroidal galaxy have been put into...
