A collection of bounds on primordial black holes (PBHs) and code for plotting them.
The list of available, tabulated bounds is in the bounds/ folder. The fact that I've included or omitted a particular bound shouldn't be taken as an endorsement or otherwise. I'll leave the user to exercise their own judgement when choosing which bounds are relevant. Note also that some of the bounds plotted above as dashed lines are projections.
If you'd like to add a bound to the repo, you can submit a pull request, create an issue or just contact me directly.
Some example plots summarising the bounds are in the plots/ folder.
You can produce a plot with
python PlotPBHbounds.py -listfile LIST_FILE -outfile OUT_FILE
where LIST_FILE is a text file containing a list of bounds to be plotted (see listfiles/list_all.txt for an example) and OUT_FILE is the full filename of the image to be output (e.g. plots/PBHbounds.pdf). You can use the short flags -lf and -of for specifying the list file and output file.
The plot style and some of the bounds are inspired by arXiv:1801.00808.
Version 1.0 (12/11/2019): Release version. Created for the first GW4FP workshop (Amsterdam 2019).
Updates:
- 20/07/2020: Substantial updates, to coincide with PBH review article (more details to follow).
- 07/01/2020: added bounds on PBH evaporation from 511 keV gamma ray line
Feel free to use the bounds and code for anything you like, but please link to the repo if you do and cite the DOI: 10.5281/zenodo.3538999.
