Description

Dataset to accompany the publication entitled "The impact of binary stars on the dust and metal evolution of galaxies" by R. M. Yates, D. Hendriks, A. P. Vijayan, R. G. Izzard, P. A. Thomas, and P. Das.

 

The L-Galaxies files included in this dataset were generated from the MM+binaryC and MM+singleStars versions of L-Galaxies, run in snapshot mode on representative sub-volumes of the Millennium-I and Millennium-II simulations, with the LITE_OUTPUT switch turned on. In detail:

 

MM+binaryC version:

SA_MM+binaryC_MRI_z0.00_0-5: Zip file containing output files (in binary format) for the MM+binaryC version of L-Galaxies in snapshot mode, run on treefiles 0-5 of Millennium-I at redshift 0.00.

 

SA_MM+binaryC_MRI_z0.00-8.22_0-5: Zip file containing output files (in binary format) for the MM+binaryC version of L-Galaxies in snapshot mode, run on treefiles 0-5 of Millennium-I at nine selected redshifts from 0.00 to 8.22.

 

SA_MM+binaryC_MRII_z#.##_40-79: Zip files containing output files (in binary format) for the MM+binaryC version of L-Galaxies in snapshot mode, run on treefiles 40-79 of Millennium-II at redshift #.## = [0.00,1.04,2.07,3.11,3.95,5.03,5.92,6.97,8.22].

 

 

MM+singleStars version:

SA_MM+singleStars_MRI_z0.00_0-5: Zip file containing output files (in binary format) for the MM+singleStars version of L-Galaxies in snapshot mode, run on treefiles 0-5 of Millennium-I at redshift 0.00.

 

SA_MM+singleStars_MRI_z0.00-8.22_0-5: Zip file containing output files (in binary format) for the MM+singleStars version of L-Galaxies in snapshot mode, run on treefiles 0-5 of Millennium-I at nine selected redshifts from 0.00 to 8.22.

 

SA_MM+singleStars_MRII_z#.##_40-79: Zip files containing output files (in binary format) for the MM+singleStars version of L-Galaxies in snapshot mode, run on treefiles 40-79 of Millennium-II at redshift #.## = [0.00,1.04,2.07,3.11,3.95,5.03,5.92,6.97,8.22].

 

 

Other:
L-Galaxies_and_binaryC_processing:

a) A set of simple python scripts to read the L-Galaxies outputs, process them into samples (as python "dictionaries"), and make some plots (including those presented in Yates+23). To use, place the desired output files into the /output folder, and execute main_lgals.py. Switches are provided at the top of main_lgals.py to modify functionality. The relevant data structure for python is also provided (LGalaxy_snapshots_liteOutput.py), as are conversions between snapshot number, redshift, and other properties for Millennium-I and Millennium-II snapshots for reference (Millennium_Planck1_Snapshots_Redshifts.txt and MillenniumII_Planck1_Snapshots_Redshifts.txt). For catalogues containing star formation histories, the corresponding times and widths of each bin are read from Database_SFH_table.fits.

b) The binaryC ensemble files used in Yates+23 are included, along with a script to read these ensemble files and generate L-Galaxies yield tables from them (process_binaryc_outputs.py). Switches are provided at the top of process_binaryc_outputs.py to modify functionality.
