abstract

Fast radio bursts (FRBs) are millisecond-duration pulses of radio emission originating from extragalactic distances. Radio dispersion on each burst is imparted by intervening plasma mostly located in the intergalactic medium. We observe a burst, FRB 20220610A, in a morphologically complex host galaxy system at redshift $z=1.016 \pm 0.002$. The burst redshift and dispersion are consistent with passage through a substantial column of material from the intergalactic medium. The burst shows evidence for passage through additional turbulent magnetized plasma, potentially associated with the host galaxy. We use the burst energy of $2 \times 10^{42}$ erg, to revise the maximum energy of an FRB.

  1. The One-Loop Power Spectrum of Fast Radio Burst Dispersion Measures

    astro-ph.CO 2026-08 accept novelty 7.0 of 10

    A one-loop EFT power spectrum model for FRB free-electron clustering matches FLAMINGO simulations to k ~ 0.2 h/Mpc, with electron bias b_e ~ 0.92 and near-perfect electron-matter correlation.

    astro-ph.HE 2025-07 conditional novelty 5.0 of 10

    H.E.S.S. found no very high energy gamma-ray counterpart to targeted fast radio bursts, setting 99% confidence upper limits on their luminosity of 10^44 to 10^48 erg/s.

  3. Probing Primordial Black Holes with upcoming Radio Telescopes: a case study for LOFAR2.0, FAST Core Array and BINGO

    astro-ph.CO 2026-04 unverdicted novelty 4.0 of 10

    LOFAR2.0, FAST Core Array and BINGO can constrain the PBH dark matter fraction f_PBH below 0.16-0.39 for masses above 10^{-2} to 10 solar masses via FRB lensing statistics.
