Luminous Radio Emission from the Superluminous Supernova 2017ens at 3.3 yr after Explosion
The Astrophysical Journal Letters, 2023 We present the results from a multiyear radio campaign of the superluminous supernova (SLSN) SN 2017ens, which yielded the earliest radio detection of an SLSN to date at the age of ∼3.3 yr after explosion. SN 2017ens was not detected at radio frequencies

The Evolution of Extragalactic Radio Sources [PDF]
Symposium - International Astronomical Union, 1996 A series of VLBI surveys of complete samples of radio sources selected at 5 GHz (Pearson & Readhead 1988, hereafter PR; Xu et al. 1995 and references therein) has revealed that ≃ 10% of the objects are “Compact Symmetric Objects” (CSOs), in which high-luminosity radio emission regions are seen on both sides of the center of activity on scales less ...

A galactic microquasar mimicking winged radio galaxies
Nature Communications, 2017 Winged radio galaxies possess wing features detectable at radio wavelengths, yet the physical interpretation of such extragalactic radio sources remains elusive.

Spectral ageing in the lobes of FR-II radio galaxies: new methods of analysis for broad-band radio data [PDF]
, 2013 The broad-bandwidth capabilities of next generation telescopes such as the Jansky Very Large Array (JVLA) mean that the spectrum of any given source varies significantly within the bandwidth of any given observation.

An Old Fogey’s History of Radio Jets
Galaxies, 2017 This paper describes a personal view of the discovery of radio jets in celestial radio sources. The existence of narrow, collimated optical features in distant objects has been known about since the early 20th century; however, the advent of radio ...

Extragalactic Radio Sources as a Piece of the Cosmological Jigsaw [PDF]
, 2018 Early on, extragalactic radio sources have pointed to a cosmologically evolv- ing Universe. They were also an important piece of evidence for the existence of supermassive black holes, now thought to be a key component of galaxies.

Powerful Radio Sources in the Southern Sky. III. First Results of the Optical Spectroscopic Campaign
The Astrophysical Journal Supplement SeriesWe recently built the G4Jy-3CRE catalog of extragalactic radio sources. This catalog lists 264 powerful radio sources selected with similar criteria to those of the revised Third Cambridge Catalog, but visible from the Southern Hemisphere.
