LOFAR discovery and wide-band characterisation of an ultra-steep spectrum AGN radio remnant associated with Abell 1318
A. Shulevski, M. Brienza, F. Massaro +15
We present the discovery of a very extended (550 kpc) and low-surface-brightness ( at 144 MHz) radio emission region in Abell 1318. These propert…
No strong radio absorption detected in the low-frequency spectra of radio-loud quasars at z > 5.6
A. J. Gloudemans, A. Saxena, H. Intema +7
We present the low-frequency radio spectra of 9 high-redshift quasars at using the Giant Metre Radio Telescope band-3, -4, and -5 observations (300-1200…
Barbell-shaped giant radio galaxy with ~100 kpc kink in the jet
Pratik Dabhade, Timothy W. Shimwell, Joydeep Bagchi +8
We present for the first time a study of peculiar giant radio galaxy (GRG) J223301+131502 using deep multi-frequency radio observations from GMRT (323, 612, and 1300 MHz) and LOFAR…
The radio spectral turnover of radio-loud quasars at
Yali Shao, Jeff Wagg, Ran Wang +8
We present Karl G. Jansky Very Large Array (VLA) S- (2--4 GHz), C- (4--8 GHz), and X-band (8--12 GHz) continuum observations toward seven radio-loud quasars at . This sample h…
Investigation of the double-lobed sources of the Cygnus constellation core
J. Saponara, P. Benaglia, I. Andruchow +2
We present a collection of double-lobed sources towards a 20 sq deg area of the Cygnus region at the northern sky, observed at 325 and 610~MHz with the Giant Metrewave Radio Telesc…
LOFAR imaging of Cygnus A -- Direct detection of a turnover in the hotspot radio spectra
J. P. McKean, L. E. H. Godfrey, S. Vegetti +75
The low-frequency radio spectra of the hotspots within powerful radio galaxies can provide valuable information about the physical processes operating at the site of the jet termin…
