Optical and radio properties of extragalactic radio sources with recurrent jet activity [PDF]
, 2017 We present a sample of 74 radio sources with recurrent jet activity. The sample consists of 67 galaxies, 2 quasars and 5 unidentified sources, selected from the published data or are newly recognized.

Kinematics and physical conditions of HI in nearby radio sources. The last survey of the old Westerbork Synthesis Radio Telescope [PDF]
, 2017 We present an analysis of the properties of neutral hydrogen (HI) in 248 nearby (0.0230$ mJy and for which optical spectroscopy is available. The observations were carried out with the Westerbork Synthesis Radio Telescope as the last large project before

The Relationship Between Beam Power and Radio Power for Classical Double Radio Sources [PDF]
, 2012 Beam power is a fundamental parameter that describes, in part, the state of a supermassive black hole system. Determining the beam powers of powerful classical double radio sources requires substantial observing time, so it would be useful to determine ...

An Updated Catalog of Giant Radio Sources [PDF]
Astrophysical Journal Supplement Series, 2018 We present a catalog of 349 giant radio sources (GRSs including both galaxies and quasars). The database contains all giants known to date from the literature. These GRSs cover the redshift range of 0.016 < z < 3.22 and include radio sources of projected

Frequency-dependent polarization of repeating fast radio bursts—implications for their origin [PDF]
Science, 2022 The polarization of fast radio bursts (FRBs), which are bright astronomical transient phenomena, contains information about their environments. Using wide-band observations with two telescopes, we report polarization measurements of five repeating FRBs ...

Extragalactic Peaked-spectrum Radio Sources at Low Frequencies [PDF]
, 2017 We present a sample of 1483 sources that display spectral peaks between 72 MHz and 1.4 GHz, selected from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey.

CHIME/FRB Discovery of Eight New Repeating Fast Radio Burst Sources [PDF]
Astrophysical Journal, 2019 We report on the discovery of eight repeating fast radio burst (FRB) sources found using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope. These sources span a dispersion measure (DM) range of 103.5–1281 pc cm−3.

A fast radio burst associated with a Galactic magnetar [PDF]
Nature, 2020 Since their discovery in 20071, much effort has been devoted to uncovering the sources of the extragalactic, millisecond-duration fast radio bursts (FRBs)2. A class of neutron stars known as magnetars is a leading candidate source of FRBs3,4.

On the nature of bright compact radio sources at z > 4.5 [PDF]
, 2016 High-redshift radio-loud quasars are used to, among other things, test the predictions of cosmological models, set constraints on black hole growth in the early universe and understand galaxy evolution. Prior to this paper, 20 extragalactic radio sources
