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 ...

Heywood, I.; Jarvis, M. J.; Hale, C. L.; Whittam, I. H.; Bester, H. L.; Hugo, B.; Kenyon, J. S.; Prescott, M.; Smirnov, O. M.; Tasse, C.; Afonso, J. M.; Best, P. N.; Collier, J. D.; Deane, R. P.; Frank, B. S.; Hardcastle, M. J.; Knowles, K.; Maddox, N.; Murphy, E. J.; Prandoni, I.; Randriamampandry, S. M.; Santos, M. G.; Sekhar, S.; Tabatabaei, F.; Taylor, A. R.; Thorat, K. (2021-10-21)

MIGHTEE is a galaxy evolution survey using simultaneous radio continuum, spectro-polarimetry, and spectral line observations from the South African MeerKAT telescope. When complete, the survey will image $\sim$20 deg$^{2}$ ...

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 eROSITA Final Equatorial-Depth Survey (eFEDS). LOFAR view of brightest cluster galaxies and AGN feedback

Pasini, T.; Brüggen, M.; Hoang, D. H.; Ghirardini, V.; Bulbul, E.; Klein, M.; Liu, A.; Shimwell, T. W.; Hardcastle, M. J.; Williams, W. L.; Botteon, A.; Gastaldello, F.; Weeren, R. J. van; Merloni, A.; Gasperin, F. de; Bahar, Y. E.; Pacaud, F.; Ramos-Ceja, M. (2021-07-06)

Context. During the performance verification phase of the Spectrum-Roentgen-Gamma (SRG) eROSITA telescope, the eROSITA Final Equatorial-Depth Survey (eFEDS) was carried out. It covers a 140 deg2 field located at 126◦ < ...

The contribution of discrete sources to the sky temperature at 144 MHz

Hardcastle, M. J.; Shimwell, T. W.; Tasse, C.; Best, P. N.; Drabent, A.; Jarvis, M. J.; Prandoni, I.; Rottgering, H. J. A.; Sabater, J.; Schwarz, D. J. (2021-04-07)

In recent years, the level of the extragalactic radio background has become a point of considerable interest, with some lines of argument pointing to an entirely new cosmological synchrotron background. The contribution ...
