A bright millisecond radio burst of extragalactic origin

abstract
Pulsar surveys offer one of the few opportunities to monitor even a small fraction (~0.00001) of the radio sky for impulsive burst-like events with millisecond durations. In analysis of archival survey data, we have discovered a 30-Jy dispersed burst of duration <5 ms located three degrees from the Small Magellanic Cloud. The burst properties argue against a physical association with our Galaxy or the Small Magellanic Cloud. Current models for the free electron content in the Universe imply a distance to the burst of <1 Gpc No further bursts are seen in 90-hr of additional observations, implying that it was a singular event such as a supernova or coalescence of relativistic objects. Hundreds of similar events could occur every day and act as insightful cosmological probes.

Kilohertz gravitational waves from a neutron star merger convert to electromagnetic waves near a magnetar via the Gertsenshtein-Zeldovich effect and are inverse Compton scattered to gigahertz frequencies to explain the associated fast radio burst.
Strong EM waves in pair plasmas are governed by nonlinearity parameter ε_p, producing attenuation over ε_p^{-2/3} wavelengths when small and shock formation when large.
Nonlinear Alfven waves with k near k0 in highly magnetized pair plasmas experience strong modulational instability that drives density fluctuations and generates high-frequency modes.
An MCMC-based period search method recovers previously reported candidate periods in FRB 20201124A observations.
Nonlinear relativistic EM waves in magnetized plasmas show modified dispersion relations where subluminal modes terminate at finite frequency when wave electric field exceeds guide field B0, preventing further propagation.
FRB dispersion measures combined with non-parametric H(z) reconstruction yield Ω_b h² = 0.02236 ± 0.00090, agreeing with BBN and Planck CMB to within 0.05%.
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.
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.
Gravitational vacuum polarization explains the Hubble tension by increasing direct H0 measurements while leaving indirect ones unaffected, does not impact the sigma8 tension, and predicts FRB measurements match CMB/BAO values.
The Arecibo telescope advanced radio astronomy via serendipitous discoveries and successive upgrades to its reflector, optics, receivers, and data systems over its operational lifetime.
