TIGRESS public data release

TIGRESS public data release#

Jupyter Book Badge

Data Download#

Full data can be downloaded via Globus.

A few data files used in the tutorials is also available at this webpage.

You can browse and download whole datasets as well as individual files. However, you will need to preserve the file structure (folders and sub-folders) for the scripts provided here to work properly.

Currently, this data release only contains the solar neighborhood models, R8, for selected snapshots with an interval of about 10 Myr after a quasi-steady state is reached. Full MHD snapshots for every 1 Myr are available upon request.

Installation of scripts#

The python scripts and example notebooks are available at the GitHub repository.

git clone git@github.com:PrincetonUniversity/astro-tigress.git

For document building, we use jupyter-book

PYTHONPATH=./ jupyter-book build docs

Quickstart#

import astro_tigress
dir_master = ... # master path to your data
model_id = "R8_2pc"
model=astro_tigress.Model(model_id,dir_master)
model.load(300,"MHD")

# make plots using yt
import yt
slc=yt.SlicePlot(model.MHD.ytds,'z',fields=('gas','nH'))
slc.annotate_magnetic_field()

Data types#

  • MHD: Small box (z=+-512 pc) original TIGRESS output for MHD variables including density, pressure, velocity (vector), and magnetic field (vector). Athena VTK format.

  • MHD_PI: Full box (z=+-3072 pc) MHD data plus electron abundance as a result of UV radiation post-processing. Athena VTK format.

  • chem: The chemistry post-processing small box output for molecular hydrogen and CO abundances. Athena++ HDF5 format.

  • CO_lines: The CO lines, J(1-0) and J(2-1). RADMC-3D binary format.

Note that the chemistry post-processing data is only available for R8-2pc.
