Effects of thermohaline instability and rotation-induced mixing on the evolution of light elements in the Galaxy : D, 3He and 4He [PDF]
Recent studies of low- and intermediate-mass stars show that the evolution of the chemical elements in these stars is very different from that proposed by standard stellar models.

Star cluster formation in cosmological simulations – III. Dynamical and chemical evolution [PDF]
In previous papers of this series, we developed a new algorithm for modeling the formation of star clusters in galaxy formation simulations. Here we investigate how dissolution of bound star clusters affects the shape of the cluster mass function and the

Stellar populations in gas-rich galaxy mergers I. Dependence on star formation history
We investigate the nature of stellar populations of major galaxy mergers between late-type spirals considerably abundant in interstellar medium by performing numerical simulations designed to solve both the dynamical and chemical evolution in a self ...

Effects of Supernova Feedback on the Formation of Galaxies [PDF]
We study the effects of Supernova (SN) feedback on the formation of galaxies using hydrodynamical simulations in a Lambda-CDM cosmology. We use an extended version of the code GADGET-2 which includes chemical enrichment and energy feedback by Type II and

Chemical evolution of disc galaxies from cosmological simulations [PDF]
We perform a suite of cosmological hydrodynamical simulations of disc galaxies, with zoomed-in initial conditions leading to the formation of a halo of mass $M_{\rm halo, \, DM} \simeq 2 \cdot 10^{12}$ M$_{\odot}$ at redshift $z=0$. These simulations aim

The Chemical Evolution of Galaxies [PDF]
The gas-phase oxygen abundance, i.e. metallicity, of a galaxy is set by the interplay between star formation and gas flows. Metals are dispersed into the interstellar medium by stellar winds and supernovae. Metals accumulate in the interstellar medium of star-forming galaxies and provide a record of star-formation.

He abundances in disc galaxies. I. Predictions from cosmological chemodynamical simulations [PDF]
Accepted for publication in A&AWe 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.

From ‘bathtub’ galaxy evolution models to metallicity gradients [PDF]
We model gas phase metallicity radial profiles of galaxies in the local Universe by building on the `bathtub' chemical evolution formalism - where a galaxy's gas content is determined by the interplay between inflow, star formation and outflows.

In this work we have simulated the evolution of disk and dwarf galaxies gravitating system, using our viscosity algorithm. We investigated changes in disk galaxy chemical abundance due to minor merger of dwarf galaxy with lower abundance of heavy ...
