On the Constraints on Superconducting Cosmic Strings from 21-cm Cosmology (supplementary inference products)

Description

These are the nested sampling inference products that were used to compute the results for arXiv:2312.08828.

The python script, and utility functions, required to produce most of the figures in the paper are included to demonstrate usage. Plotting script for functional posteriors are not included as these require emulators that are not part of this data release. 

All the included chains were computed using PolyChordLite .

Chain foldername conventions:

  • HERA: Constraints from HERA Phase I 21-cm power spectrum upper limits
  • SARAS_3: Constraints from the SARAS 3 21-cm global signal null detecetion
  • Xray_Background: Constraints from collated measurements of the unresolved X-ray background
  • HERA_SARAS_3_Xray_Background: Joint analysis of the above

Chains have rootnames that are of the form 'foldername_constraints'. See arXiv:2312.08828 for additional details on each of the model parameters. 

Software used: numpy, pandas, pyYAML, scipy, globalemu, matplotlib, tensorflow, scikit-learn, joblib, pypolychord, anesthetic, hera-pspec, seaborn, margarine, fgivenx, tqdm

Exact software versions are specified in an included requirements.txt file for reproducibility.
