Radio source-component association for the LOFAR Two-metre Sky Survey with region-based convolutional neural networks
Rafaël I. J. Mostert, Kenneth J. Duncan, Lara Alegre +5
Radio loud active galactic nuclei (RLAGNs) are often morphologically complex objects that can consist of multiple, spatially separated, components. Astronomers often rely on visual…
Cosmic evolution of low-excitation radio galaxies in the LOFAR Two-meter Sky Survey Deep Fields
R. Kondapally, P. N. Best, R. K. Cochrane +16
Feedback from low-excitation radio galaxies (LERGs) plays a key role in the lifecycle of massive galaxies in the local Universe; their evolution, and the impact of these active gal…
The LOFAR Two-metre Sky Survey -- V. Second data release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +103
In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…
Accretion mode versus radio morphology in the LOFAR Deep Fields
B. Mingo, J. H. Croston, P. N. Best +17
Radio-loud active galaxies have two accretion modes [radiatively inefficient (RI) and radiatively efficient (RE)], with distinct optical and infrared signatures, and two jet dynami…
The discovery of a radio galaxy of at least 5 Mpc
Martijn S. S. L. Oei, Reinout J. van Weeren, Martin J. Hardcastle +9
We discover what is in projection the largest known structure of galactic origin: a giant radio galaxy with a projected proper length of . The source,…
