Radio galaxies and feedback from AGN jets
(2020-07-31)
We review current understanding of the population of radio galaxies and radio-loud quasars from an observational perspective, focusing on their large-scale structures and dynamics. We discuss the physical conditions in ...
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 ...
Coherent radio emission from a quiescent red dwarf indicative of star-planet interaction
(2020-02-17)
Low-frequency (ν ≲ 150 MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission from the Sun has been used to study coronal structure, ...
