The best of both worlds: Combining LOFAR and Apertif to derive resolved radio spectral index images
R. Morganti, T. A. Oosterloo, M. Brienza +36
Supermassive black holes at the centres of galaxies can cycle through periods of activity and quiescence. Characterising the duty cycle of active galactic nuclei is crucial for und…
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…
Discovery of a radio galaxy at z = 5.72
A. Saxena, M. Marinello, R. A. Overzier +11
We report the discovery of the most distant radio galaxy to date, TGSS1530 at a redshift of close to the presumed end of the Epoch of Reionisation. The radio galaxy was se…
LOFAR low-band antenna observations of the 3C295 and Bootes fields: source counts and ultra-steep spectrum sources
R. J. van Weeren, W. L. Williams, C. Tasse +98
We present LOFAR Low Band observations of the Bootes and 3C295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy beam, making them the dee…
