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.

SPOTLIGHT is a new real-time multibeam transient search pipeline for uGMRT using 90 A100 GPUs that detected 2870 bursts from 42 sources with sensitivity matching the predicted ~0.2 Jy ms threshold.
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.
CASM-256 is a new 256-antenna radio array at Owens Valley that uses real-time digital beamforming to search for fast radio bursts and galactic transients over a huge sky area.
A 9-hour FAST observation covering ~4230 GCs in M49 found no FRBs and sets an upper limit of 4.7e-4 FRB GC^-1 hr^-1 above ~16.5 mJy ms fluence.
LAMBDA proposes megameter-scale baselines using additional Australian stations to extend SKA-Low for high-resolution low-frequency VLBI.
The BURSTT back-end system achieves real-time multi-stage beamforming and de-dispersion search to detect FRBs and trigger VLBI localization using RFSoC and optimized server processing.
FRBs serve as cosmological probes via dispersion measure, scattering, and Faraday rotation to constrain baryon distribution, expansion history, magnetic fields, and fundamental physics effects.
This review summarizes FRB properties and outlines how SKA capabilities will help identify progenitors and enable cosmological applications.
