Generalizing the host galaxy dispersion measure distribution in FRB cosmology with 125 events produces Hubble constant estimates consistent with Planck 2018 and SH0ES while strongly favoring these models over narrow-prior alternatives on feedback strength.

Generalized Distributions of Host Dispersion Measures in the Fast Radio Burst Cosmology
Generalizing the host galaxy dispersion measure distribution in FRB cosmology with 125 events produces Hubble constant estimates consistent with Planck 2018 and SH0ES while strongly favoring these models over narrow-prior alternatives on feedback strength.
