PBHbounds

DOI License: MIT

A collection of bounds on primordial black holes (PBHs) and code for plotting them.

Messy summary of all PBH bounds

Bounds

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.

Plots

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.

Versions

Version 1.0 (12/11/2019): Release version. Created for the first GW4FP workshop (Amsterdam 2019).
