The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
Unified models revisited I: modelling the effect of source geometry on radio galaxy/quasar unification
Siddhant Pinjarkar, Martin J. Hardcastle, Jonathon C. S. Pierce +1
The orientation-based unification model proposes that radio-loud quasars and radio galaxies are the same objects observed at different angles. A key prediction of this model is tha…
Radio AGN selection in LoTSS DR2
M. J. Hardcastle, J. C. S. Pierce, K. J. Duncan +6
The wide-area component of the LOFAR Two-Metre Sky Survey (LoTSS) is currently the largest radio survey ever carried out, and a large fraction of the 4.5 million radio sources it c…
The nature of HERGs and LERGs in LoTSS DR2 a morphological perspective
J. Chilufya, M. J. Hardcastle, J. C. S. Pierce +4
We present the largest visually selected sample of extended (60 arcsec) radio-loud active galactic nuclei (RLAGN) to date, based on the LOw-Frequency Array Two-Metre Sky Survey…
