The LOFAR view of NGC 3998, a sputtering AGN
Sarrvesh S. Sridhar, Raffaella Morganti, Kristina Nyland +3
Low-power radio sources dominate the radio sky. They tend to be small in size and core-dominated, but the origin of their properties and the evolution of their radio plasma are not…
Investigating the spectral age problem with powerful radio galaxies
Vijay H. Mahatma, Martin J. Hardcastle, Judith H. Croston +3
The 'spectral age problem' is our systematic inability to reconcile the maximum cooling time of radiating electrons in the lobes of a radio galaxy with its age as modelled by the d…
Unveiling the cause of hybrid morphology radio sources (HyMoRS)
Jeremy J. Harwood, Tessa Vernstrom, Andra Stroe
Hybrid morphology radio sources (HyMoRS) are a rare group of radio galaxies in which differing Fanaroff & Riley morphologies (FR I/II) are observed for each of the two lobes. While…
LOFAR first look at the giant radio galaxy 3C 236
A. Shulevski, P. D. Barthel, R. Morganti +8
We have examined the giant radio galaxy 3C~236 using LOFAR at 143 MHz down to an angular resolution of 7", in combination with observations at higher frequencies. We have used the…
Signatures from a merging galaxy cluster and its AGN population: LOFAR observations of Abell 1682
A. O. Clarke, A. M. M. Scaife, T. Shimwell +13
We present LOFAR data from 110--180~MHz of the merging galaxy cluster Abell 1682, alongside archival optical, radio and X-ray data. Our 6 arc-second resolution images at low freque…
