The Cosmic Evolution of Fast Radio Bursts Inferred from the CHIME/FRB Baseband Catalog 1
The Astrophysical JournalRedshift and luminosity distributions are essential for understanding the cosmic evolution of extragalactic objects and phenomena, such as galaxies, gamma-ray bursts, and fast radio bursts (FRBs).

The Variability of Persistent Radio Sources of Fast Radio Bursts
The Astrophysical JournalOver 700 bright millisecond-duration radio transients, known as fast radio bursts (FRBs), have been identified to date. Nevertheless, the origin of FRBs remains unknown.

A Deep VLA Search for a Persistent Radio Counterpart to the One-off FRB 20250316A
The Astrophysical Journal LettersFast radio burst (FRB) 20250316A, detected by CHIME on 2025 March 16 with a fluence of 1.7 ± 0.1 kJy ms and a dispersion measure of 161.3 ± 0.4 pc cm ^−3 , ranks among the brightest extragalactic FRBs at ∼40 Mpc. We obtain deep Karl G.

Symposium - International Astronomical Union, 1981 The understanding of the nature of strong radio emission associated with galaxies and quasars has significantly increased in the last five years. A large contribution to this increase has been obtained from the arcsec and milli-arcsec mapping of radio sources which show remarkable features.

The nature of the radio sources [PDF]
Symposium - International Astronomical Union, 1959 Optical search in the positions of radio sources has led to the certain identification of some eight sources with galactic nebulosities, and nineteen with extragalactic nebulae.

The Astrophysical JournalThe radiation physics of fast radio bursts (FRBs) remains an open question. Current observations have discovered that narrowly banded bursts of FRB 20201124A are active in 0.4–2 GHz, and their spectral peak frequency ( ${\nu }_{p}^{\mathrm{obs}}$ ) is ...

Statistical and Temporal Analysis of Multicomponent Burst Clusters from the Repeating FRB 20190520B
The Astrophysical JournalFast radio bursts (FRBs) are bright, millisecond-duration extragalactic radio transients that probe extreme astrophysical environments. Many FRBs exhibit multicomponent structures, which encode information about their emission mechanisms or progenitor ...

Radio sources with ultra-high polarization
, 2010 A sample of 129 unresolved radio sources with ultrahigh linear polarization (>30 per cent) has been selected from the NRAO VLA Sky Survey. Such high average linear polarization is unusual in extragalactic sources. Higher resolution Australia Telescope Compact Array and Very Large Array observations confirm the high average polarization but find that

The Astrophysical JournalVariations in the Faraday rotation measure (RM) of repeating fast radio bursts (FRBs) provide critical diagnostics of the dynamically evolving magnetoionic environments surrounding their progenitors. Sudden, transient “RM flares” can trace the passage of
