He abundances in disc galaxies. I. Predictions from cosmological chemodynamical simulations
We investigate how the stellar and gas-phase He abundances evolve as a function of time within simulated star-forming disc galaxies with different star formation histories. We make use of a cosmological chemodynamical ...
The COMBS survey I : Chemical Origins of Metal-Poor Stars in the Galactic Bulge
Chemistry and kinematic studies can determine the origins of stellar population across the Milky Way. The metallicity distribution function of the bulge indicates that it comprises multiple populations, the more metal-poor ...
Zoom-in cosmological hydrodynamical simulation of a star-forming barred, spiral galaxy at redshift z=2
We present gas and stellar kinematics of a high-resolution zoom-in cosmological chemodynamical simulation, which fortuitously captures the formation and evolution of a star-forming barred spiral galaxy, from redshift ...
The metallicity and elemental abundance maps of kinematically atypical galaxies for constraining minor merger and accretion histories
Explaining the internal distribution and motions of stars and gas in galaxies is a key aspect in understanding their evolution. In previous work we identified five well-resolved galaxies with atypical kinematics from a ...
