Forward modeling of 90 localized FRBs from DSA and ASKAP yields n_z = 1.62^{+1.48}_{-1.57} for DM_host(z) ∝ (1+z)^{n_z}, excluding n_z=0 at 1σ.

A differential DM method using same-sky localized FRBs removes Milky Way contributions without Galactic models and produces a different constraint on Γ ≡ Ω_b H_0 f_d from current data compared to conventional approaches.
FRB DMs correlate at 2.6-5 sigma with galaxies, weak lensing, CIB, CMB lensing, tSZ, X-ray clusters, SXRB and radio continuum, consistent with moderate feedback models while ruling out weak feedback at 3.5 sigma via SXRB-DM.
FRB dispersion measures from CHIME/FRB Outrigger constrain gas mass fractions in galaxy groups and clusters, consistent with eROSITA at R500 but with mild tension at R200.
Forecasts indicate SKA FRB observations can constrain baryonic feedback models, measure circumgalactic medium properties, and aid reionization studies through DM statistics and scattering timescales.
Forecasts using mock CSST lensing and SKA/DSA-2000 FRB DM data show joint analysis improves log10 T_AGN precision from 3.1% to 0.4% and tightens sum m_nu upper limit to <0.47 eV.
PATH is extended with three fitted P(m_r|z) prior models combined with P(z|DM), raising host-association confidence for ASKAP FRBs while showing fainter-than-expected host magnitude distribution.
z-DM modeling of multiple FRB surveys constrains minimum burst energy to log E_min = 39.49^{+0.39}_{-1.48} erg and predicts 25-41% of FAST FRBs at z ≳ 2.
The PINK updates enhance the CELEBI FRB pipeline with better astrometry, time-frequency gating, polarization calibration, DM optimization tools, and a software container for improved efficiency and localization of events like FRB 20251019A.
FRBs serve as cosmological probes via dispersion measure, scattering, and Faraday rotation to constrain baryon distribution, expansion history, magnetic fields, and fundamental physics effects.
A review of late-universe models concludes that DESI BAO plus uncalibrated supernovae data indicate the Hubble tension originates in new low-redshift physics.
A reported periodic fast radio burst is reclassified as Galactic pulsar emission due to CHIME calibration and beam-pointing error.
