pbhstat: A Python package for calculating the primordial black hole abundance
Philippa S. Cole, Jacopo Fumagalli
We present pbhstat, a publicly available Python package designed to compute the mass function and total abundance of primordial black holes (PBHs) from a given primordial power spe…

Haloes, other dark matter candidates and astrophysical implications
Philippa S. Cole
It is possible that a multi-component dark matter model is required if primordial black holes only contribute to a fraction of the energy density in dark matter. This is increasing…

Smooth vs instant inflationary transitions: steepest growth re-examined and primordial black holes
Philippa S. Cole, Andrew D. Gow, Christian T. Byrnes +1
Primordial black holes (PBHs) can be produced by a range of mechanisms in the early universe. A particular formation channel that connects PBHs with inflationary phenomenology invo…
