Combining 104 FRBs with CC, SNe, and BAO data yields 10-43% tighter constraints on Omega_b, H0, and dark energy parameters in LambdaCDM, wCDM, CPL, and three f(R) models, with modest preference for extensions over LambdaCDM.
Cosmographic constraints from 106 FRBs on H0, q0, j0 depend sensitively on whether a Gaussian or quasi-Gaussian PDF is assumed for DM_IGM and on whether the baryon mass fraction is fixed or free.
LOFAR2.0, FAST Core Array and BINGO are forecast to bound f_PBH < 0.16 (M>1 Msun), <0.39 (M>10 Msun) and <0.39 (M>0.1 Msun) respectively from null FRB lensing.

The impact of FRB dispersion measure probability distribution functions on cosmographic estimates
Cosmographic constraints from 106 FRBs on H0, q0, j0 depend sensitively on whether a Gaussian or quasi-Gaussian PDF is assumed for DM_IGM and on whether the baryon mass fraction is fixed or free.
