LOFAR-Boötes: Properties of high- and low-excitation radio galaxies at
W. L. Williams, G. Calistro Rivera, P. N. Best +13
This paper presents a study of the redshift evolution of radio-loud active galactic nuclei (AGN) as a function of the properties of their galaxy hosts in the Boötes field. To achie…
The LOFAR window on star-forming galaxies and AGN - curved radio SEDs and IR-radio correlation at
G. Calistro-Rivera, W. L. Williams, M. J. Hardcastle +20
We present a study of the low-frequency radio properties of star forming (SF) galaxies and active galactic nuclei (AGN) up to redshift . The new spectral window probed by th…
Investigating the Unification of LOFAR-detected powerful AGN in the Boötes Field
Leah K. Morabito, W. L. Williams, Kenneth J. Duncan +17
Low radio frequency surveys are important for testing unified models of radio-loud quasars and radio galaxies. Intrinsically similar sources that are randomly oriented on the sky w…
LOFAR MSSS: Discovery of a 2.56 Mpc giant radio galaxy associated with a disturbed galaxy group
A. O. Clarke, G. Heald, T. Jarrett +40
We report on the discovery in the LOFAR Multifrequency Snapshot Sky Survey (MSSS) of a giant radio galaxy (GRG) with a projected size of Mpc projected on the sky. I…
LOFAR observations of decameter carbon radio recombination lines towards Cassiopeia A
P. Salas, J. B. R. Oonk, R. J. van Weeren +6
We present a study of carbon radio recombination lines towards Cassiopeia A using LOFAR observations in the frequency range 10-33 MHz. Individual carbon lines are detected in a…
