Chemodynamical Simulations of the Milky Way
Lead Research Organisation:
University of Surrey
Department Name: Physics
Abstract
Our aim is to provide a suite of chemodynamical simulations of disk galaxies within a cosmological framework, in order to interpret Galactic archaeology survey data, i.e., the kinematics and chemical abundances obtained with Gaia and spectroscopic surveys such as HERMES, WEAVE, and PFS (all of which Kobayashi is participating in), as well as pencil-beam observations of very-nearby galaxies with JWST. We will use a set of initial conditions from cosmological simulations and run zoom-in simulations with high enough resolution to resolve spatial distributions of elements. We will start with the latest nucleosynthesis yields in Kobayashi et al. (2020a), and will add the effects of stellar rotation and binaries during the project. The PDRA will also update the existing Gadget-3 based code (Vincenzo & Kobayashi 2020), using the magneto-hydrodynamical code AREPO (Springel 2010) and more advanced modelling of baryon physics. We will also use the simulations to unveil the formation and evolution of the Milky Way across cosmic time and probe the origin of elements in the universe.

| Title | Pop III Star Lyman Band Spectra |
| Description | This dataset contains the Lyman band stellar spectra of individual Pop III stars computed and utilized in the paper "Impact of the Primordial Stellar Initial Mass Function on the 21-cm Signal". In addition, we provide the photon number emissivity per stellar baryon for each of our four fiducial IMFs (shown in Figure 6 of the paper). Please consult the README.md for further details about the dataset contents, calculation, and how it is structured. |

| Title | binary_c V2.2.4 with binary_c-python V1.0.0 on Kubuntu 22.04 (Linux) desktop |
| Description | The binary_c software framework models the evolution of single, binary and multiple stars, including stellar evolution and nucleosynthesis. It is desgined for stellar population calculations, so is lightweight and versatile, and its support software contains tools for development and data analysis. binary_c is happy in standalone, virtual and HPC environments. Builds on Linux, OSX and WSL. This is version 2.2.4 of binary_c, with binary_c-python 1.0.0, installed on Kubuntu 22.04 desktop running a Linux kernel. Many useful tools are pre-installed, such as GCC, Clang, meson, ninja, valgrind, emacs, GSL, kcachegrind, gdb, gnuplot, and Jupyter so you can run binary_c-python's notebooks. Also included are commands to run either the latest stable versions or master versions straight from the gitlab repository.
