Follow-up Observations of Apparently One-off Sources from the Parkes Telescope

The Astrophysical Journal
A small fraction of fast radio bursts (FRBs) have been observed with multiple bursts, whereas most Galactic sources emitting radio pulses are known to repeat.

Selection of radio sources for Venus balloon-Pathfinder Delta-DOR navigation at 1.7 GHz [PDF]

In order to increase the success rate of the Delta-DOR (Delta-Differential One-way Range) VLBI navigational support for the French-Soviet Venus Balloon and Halley Pathfinder projects, forty-four extragalactic radio sources were observed in advance of ...

Identification of 4876 Bent-tail Radio Galaxies in the FIRST Survey Using Deep Learning Combined with Visual Inspection

The Astrophysical Journal Supplement Series
Bent-tail radio galaxies (BTRGs) are characterized by bent radio lobes. This unique shape is mainly caused by the movement of the galaxy within a cluster, during which the radio jets are deflected by the intracluster medium.

Extragalactic Radio Sources and CMB anisotropies

, 1999
Confusion noise due to extragalactic sources is a fundamental astrophysical limitation for experiments aimed at accurately determining the power spectrum of the Cosmic Microwave Background (CMB) down to arcmin angular scales and with a sensitivity $ T/T \simeq 10^{-6}$.

A JWST Paα Calibration of the Radio Luminosity–Star Formation Rate Relation at z ∼ 1.3

The Astrophysical Journal
As radio emission from normal galaxies is a dust-free tracer of star formation, tracing the star formation history of the Universe is a key goal of the Square Kilometre Array and the Next-Generation Very Large Array.

Kinematics of Extragalactic Radio Sources

, 2004
Symmetric extragalactic radio sources exhibit a baffling array of features - the remarkable symmetry between the two lobes, the emission in the radio frequency range, well collimated jets, core regions emitting blue and ultraviolet light, transient X-ray and gamma ray bursts, etc.
