Merger rate of Primordial Black holes (PBHs)

This dataset contains the total comoving merger rates in the unit of (Gpc^-3 yr^-1) as a function of redshift, for primordial black holes (PBHs) in dark matter halos with masses ranging from 10^4 M⊙ to 10^15 M⊙, assuming that all dark matter is in PBHs, i.e., fPBH = 1, and that halos are populated by PBHs.

The total rate includes three merger channels:

1.  Direct Captures: mergers via gravitational wave emission.
2. Binary-Single Interactions: binaries through interactions with single and wide binary PBHs.
3.  Unperturbed binaries residing in dark matter halos merging via gravitational wave emission.

 For channels 2 and 3, we assume fPBH,binaries = 0.5.

The total rates are provided in text files containing two columns of data [redshift, total Rate (Gpc^−3 yr^−1)] for the following two cases:

1) Monochromatic PBH mass distribution ranging from 5 M⊙ to 80 M⊙

2) lognormal PBH mass distribution with σ = 0.6 and varying and  ln(mPBH)
