LoTSS DR1: Double-double radio galaxies in the HETDEX field
V. H. Mahatma, M. J. Hardcastle, W. L. Williams +19
Double-double radio galaxies (DDRGs) represent a short but unique phase in the life-cycle of some of the most powerful radio-loud active galactic nuclei (RLAGN). These galaxies dis…
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…
LOFAR observations of the XMM-LSS field
C. L. Hale, W. Williams, M. J. Jarvis +12
We present observations of the XMM Large-Scale Structure (XMM-LSS) field observed with the LOw Frequency ARray (LOFAR) at 120-168 MHz. Centred at a J2000 declination of $-4.5^{\cir…
LoTSS/HETDEX: Optical quasars I. Low-frequency radio properties of optically selected quasars
Gülay Gürkan, Martin Hardcastle, Philip Best +17
The radio-loud/radio-quiet (RL/RQ) dichotomy in quasars is still an open question. Although it is thought that accretion onto supermassive black holes in the centre the host galaxi…
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 origin of radio emission in broad absorption line quasars: Results from the LOFAR Two-metre Sky Survey
L. K. Morabito, J. H. Matthews, P. N. Best +14
We present a study of the low-frequency radio properties of broad absorption line quasars (BALQSOs) from the LOFAR Two-metre Sky-Survey Data Release 1 (LDR1). The value-added LDR1…
