The Application of Ridgelines in Extended Radio Source Cross-Identification

Barkus, B.; Croston, J. H.; Piotrowska, J.; Mingo, B.; Best, P. N.; Hardcastle, M. J.; Mostert, R. I. J.; Röttgering, H. J. A.; Sabater, J.; Webster, B.; Williams, W. L. (2021-10-22)

Extended radio sources are an important minority population in modern deep radio surveys, because they enable detailed investigation of the physics governing radio-emitting regions such as active galaxies and their ...

Investigating the spectra and physical nature of galaxy scale jets

Webster, B.; Croston, J. H.; Harwood, J. J.; Baldi, R. D.; Hardcastle, M. J.; Mingo, B.; Rottgering, H. J. A. (2021-10-13)

Previous studies have shown that physically small, low-luminosity radio galaxies, which we refer to as galaxy scale jets (GSJ), could potentially have a significant effect upon the host galaxy's evolution. Using 6 arcsec ...

The best of both worlds : Combining LOFAR and Apertif to derive resolved radio spectral index images

Morganti, R.; Oosterloo, T. A.; Brienza, M.; Jurlin, N.; Prandoni, I.; Orru', E.; Shabala, S. S.; Adams, E. A. K.; Adebahr, B.; Best, P. N.; Coolen, A. H. W. M.; Damstra, S.; Blok, W. J.

(2021-04-07)

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 understanding the impact of the energy they ...

We present the source associations, cross-identifications, and multi-wavelength properties of the faint radio source population detected in the deep tier of the LOFAR Two Metre Sky Survey (LoTSS): the LoTSS Deep Fields. ...
