# Chemo-dynamical simulations of galaxies

## TL;DR

This paper presents chemo-dynamical galaxy simulations incorporating star formation, feedback, and chemical enrichment, revealing how hypernova feedback influences galaxy evolution and chemical properties across different galactic components.

## Contribution

It introduces a comprehensive 3D hydrodynamical model that highlights the critical role of hypernova feedback in reproducing observed galaxy properties.

## Key findings

- Hypernova feedback resolves the [Zn/Fe] problem.
- The model reproduces cosmic star formation rate history.
- Different galactic components show distinct kinematics and chemical abundances.

## Abstract

We simulate the formation and evolution of galaxies with a self-consistent 3D hydrodynamical model including star formation, supernova feedback, and chemical enrichment. Hypernova feedback plays an essential role not only in solving the [Zn/Fe] problem, but also reproducing the cosmic star formation rate history and the mass-metallicity relations. In a Milky-Way type galaxy, kinematics and chemical abundances are different in bulge, disk, and thick disk because of different star formation histories and the contribution of Type Ia Supernovae.
