Περίληψη :

I will present an analysis on the radio structure of radio AGN from the VLA-COSMOS 3GHz Large Project (JVLA-COSMOS). We classify these in FRI and FRII radio AGN based on the FR-type classification scheme, and compare them to a sample of jet-less radio AGN in JVLA-COSMOS. With the use of the photometric and multiwavelength catalogues in COSMOS we relate their radio structure to their physical properties, and in particular to their energetics (accretion mode) and environment (X-ray groups, density fields). Finally I will discuss briefly the public release of the 3 GHz VLA-COSMOS radio data ( and highlight some of the results of the recently published papers (e.g. composition of the faint radio population, and cosmic evolution of AGN).
