A second coherent radio burst spanning 704-4032 MHz with spectral index -2.18, 54% linear and 22% circular polarization, and an orthogonal polarization angle jump was detected from 2XMM J104608.7-594306, showing rare radio activity in sources thought to be radio-quiet.

No statistically significant excess of associations is found between CHIME FRBs and Swift GRBs after spatial, redshift, and temporal filtering, consistent with random coincidences.
Simulations demonstrate that Cosmic Explorer can robustly constrain cosmology and host galaxy parameters from GW-FRB associations using luminosity distance-dispersion measure relations without spectroscopic redshifts, unlike the current LIGO-Virgo network.
