Dark matter limits

The purpose of this website is to collate astrophysical (and other) limits on dark matter.
This means I need your help! Please let me know if a limit is missing or needs adjusting.
You are encouraged to use/modify these plots. Please cite Zenodo link (to follow) if you do.
Disclaimer: different limits/projections often have different uncertainties and levels of statistical rigour.

Ultra-light axions

Cosmological/astrophysical limits (two sigma) on the ultra-light axion energy density vs. particle mass.
Solid = current limit; thick line = projected limit.

Ultra-light axions (cosmological)

Cosmological limits (two sigma) on the ultra-light axion energy density vs. particle mass.
Solid = current limit; thick line = projected limit (Stage IV sensitivity)
