Abstract:
The activity of radio galaxies is now understood as a key ingredient
in the evolution of galaxies and galaxy clusters across cosmic time,
yet there are still many unknowns regarding the kinetic AGN feedback,
and the lives and growth of these radio sources. In this talk I will
focus on two aspects of this broad subject: the intermittent activity
of radio galaxies and their interaction with environments as imprinted
on their radio morphology (hybrid morphology and asymmetric radio
sources). Although detailed analyses of these rare radio sources come
predominantly from dedicated extensive follow up programs, which I
will present in this talk, the sources were preselected from all-sky
radio surveys. I will discuss the need of new, deep, wide-field
versatile radio galaxy samples from the new generation radio
facilities, and the importance of citizen science projects and
emerging machine learning algorithms in the classifications of radio
sources from large all-sky radio surveys.
