mocksurvey

Some useful tools for conducting mock surveys of galaxies from the UniverseMachine empirical model.

Author

  • Alan Pearl

Prerequisites

  • python=3.9.* or python=3.8.*
  • At the time of writing, a prerequisite (halotools>=0.7) is incompatible with python>=3.10.
  • Optional, but recommended to install Corrfunc (pip install Corrfunc)
    • Requires gsl installation (check with gsl-config --version, install with conda install -c conda-forge gsl) ### Example to automatically install prerequisites using a conda environment: conda create -n py39-mocksurvey python=3.9 gsl conda activate py39-mocksurvey pip install Corrfunc Note: If using pycorr, don't pip install Corrfunc. Instead, follow the pycorr instructions at https://py2pcf.readthedocs.io/en/latest/user/building.html

Installation and Getting Started

pip install --upgrade git+https://github.com/AlanPearl/mocksurvey.git <!-- cd /path/to/download/source/code git clone https://github.com/AlanPearl/mocksurvey pip install ./mocksurvey -->

Set path to a directory where you would like to store downloaded data

  • Make a directory, for example: mkdir -p ~/local/mocksurvey_downloads/
  • Set the path: python -m mocksurvey set-data-path ~/local/mocksurvey_downloads #### Download and install UniverseMachine source code
  • Make a directory, for example: mkdir -p ~/local/src/
  • Install UniverseMachine: cd ~/local/src git clone https://bitbucket.org/pbehroozi/universemachine cd universemachine make python -m mocksurvey config UM set-lightcone-executable ./lightcone #### Download UniverseMachine snapshots. This redshift range (0 - inf) downloads all ~300 GB. You may choose a narrower range or enter a single value to download a single snapshot. python -m mocksurvey download-um 0 inf #### Download UltraVISTA photometry python -m mocksurvey download-uvista #### [Optional] Download raw synthetic spectra to assign to mock galaxies (~30 GB) python -m mocksurvey download-uvista-mock-spectra #### Get started by building a mock survey (see Pearl et al. 2022) python -m mocksurvey lightcone [--help] #### View all commands python -m mocksurvey --help
