He abundances in disc galaxies. I. Predictions from cosmological chemodynamical simulations
(2019-10-01)
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 ...
Observability of intermittent radio sources in galaxy groups and clusters
(2018-11-11)
We have carried out numerical hydrodynamic simulations of radio jets from active galactic nuclei using the PLUTO simulation code, with the aim of investigating the effect of different environments and intermittency of ...
On the [α/Fe]-[Fe/H] relations in early-type galaxies
(2018-10-01)
We study how the predicted [α/Fe]-[Fe/H] relations in early-type galaxies vary as functions of their stellar masses, ages, and stellar velocity dispersions, by making use of cosmological chemodynamical simulations with ...
Evolution of N/O ratios in galaxies from cosmological hydrodynamical simulations
(2018-07-21)
We study the redshift evolution of the gas-phase O/H and N/O abundances, both (i) for individual interstellar medium (ISM) regions within single spatially resolved galaxies and (ii) when dealing with average abundances in ...
