Radio spectral properties and jet duty cycle in the restarted radio galaxy 3C388
(2020-06-05)
Context. Restarted radio galaxies represent a unique tool for investigating the duty cycle of the jet activity in active galactic nuclei (AGN). The radio galaxy 3C388 has long been claimed to be a peculiar example of an ...
Low-frequency observations of the Giant Radio Galaxy NGC 6251
(2020-06-01)
We present LOFAR observations at 150 MHz of the borderline FRI/FRII giant radio galaxy NGC 6251. This paper presents the most sensitive and highest-resolution images of NGC 6251 at these frequencies to date, revealing for ...
Giant radio galaxies in the LOFAR Two-metre Sky Survey-I
(2020-03-01)
Giant radio galaxies (GRGs) are a subclass of radio galaxies which have grown to megaparsec scales. GRGs are much rarer than normal sized radio galaxies ( less than 0.7 Mpc) and the reason for their gigantic sizes is still ...
