Abstract
Compact Symmetric Objects (CSO) are considered to be the young version of Fanaroff-Riley type I and type II radio galaxies, with typical sizes smaller than 1 kpc and ages of the order of a few thousand years. Before the launch of the Fermi satellite, young radio sources were predicted to emerge as a possible new gamma-ray emitting population detectable by the Large Area Telescope (LAT). After more than 6 years of Fermi operation, the question of young radio sources as gamma-ray emitting objects still remains open. In this contribution, we discuss candidate gamma-ray emitting CSO and future perspective for detecting young radio sources with Fermi-LAT. (C) 2016 WILEY-VCH Verlag GmbH & Co.
