Radio-loud AGN in the first LoTSS data release: The lifetimes and environmental impact of jet-driven sources
M. J. Hardcastle, W. L. Williams, P. N. Best +20
We constructed a sample of 23,344 radio-loud active galactic nuclei (RLAGN) from the catalogue derived from the LOFAR Two-Metre Sky Survey (LoTSS) survey of the HETDEX Spring field…
LoTSS/HETDEX: Disentangling star formation and AGN activity in gravitationally-lensed radio-quiet quasars
H. R. Stacey, J. P. McKean, N. J. Jackson +15
Determining the star-forming properties of radio-quiet quasars is important for understanding the co-evolution of star formation and black hole accretion. Here, we present the dete…
The LOFAR Two-metre Sky Survey IV. First Data Release: Photometric redshifts and rest-frame magnitudes
Kenneth J Duncan, J. Sabater, H. J. A. Röttgering +24
The LOFAR Two-metre Sky Survey (LoTSS) is a sensitive, high-resolution 120-168 MHz survey of the Northern sky. The LoTSS First Data Release (DR1) presents 424 square degrees of rad…
The LOFAR Two-metre Sky Survey (LoTSS) III. First Data Release: optical/IR identifications and value-added catalogue
W. L. Williams, M. J. Hardcastle, P. N. Best +38
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168 MHz survey of the Northern sky with diverse and ambitious science goals. Many of the scienti…
The LOFAR Two-metre Sky Survey - II. First data release
T. W. Shimwell, C. Tasse, M. J. Hardcastle +104
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168MHz survey of the entire northern sky for which observations are now 20% complete. We present…
Exoplanet Transits with Next-Generation Radio Telescopes
Benjamin J. S. Pope, Paul Withers, Joseph R. Callingham +1
Nearly everything we know about extrasolar planets to date comes from optical astronomy. While exoplanetary aurorae are predicted to be bright at low radio frequencies (< 1 GHz), w…
The Murchison Widefield Array Transients Survey (MWATS). A search for low frequency variability in a bright Southern hemisphere sample
M. E. Bell, Tara Murphy, P. J. Hancock +38
We report on a search for low-frequency radio variability in 944 bright (> 4Jy at 154 MHz) unresolved, extragalactic radio sources monitored monthly for several years with the Murc…
The MWA GLEAM 4-Jy (G4Jy) Sample
Sarah V. White, Thomas M. O. Franzen, O. Ivy Wong +15
Powerful radio-galaxies feature heavily in our understanding of galaxy evolution. However, when it comes to studying their properties as a function of redshift and/or environment,…
Galactic synchrotron distribution derived from 152 HII region absorption features in the full GLEAM survey
H. Su, J. P. Macquart, N. Hurley-Walker +22
We derive the synchrotron distribution in the Milky Way disk from HII region absorption observations over -40° < l < 40° at six frequencies of 76.2, 83.8, 91.5, 99.2, 106.9, and 11…
Extended X-ray emission in PKS 1718649
T. Beuchert, A. Rodríguez-Ardila, V. A. Moss +15
PKS 1718649 is one of the closest and most comprehensively studied candidates of a young active galactic nucleus (AGN) that is still embedded in its optical host galaxy. The com…
High-resolution Observations of Low-luminosity Gigahertz-Peaked Spectrum and Compact Steep Spectrum Sources
Jordan D. Collier, Steven J. Tingay, Joseph R. Callingham +27
We present Very Long Baseline Interferometry observations of a faint and low-luminosity ($L_{\rm 1.4 GHz} < 10^{27}~\mbox{W Hz}^{-1}$) Gigahertz-Peaked Spectrum (GPS) and Compact S…
The SAMI Galaxy Survey: gas content and interaction as the drivers of kinematic asymmetry
J. V. Bloom, S. M. Croom, J. J. Bryant +21
In order to determine the causes of kinematic asymmetry in the H gas in the SAMI Galaxy Survey sample, we investigate the comparative influences of environment and intrinsic pro…
