Abstract

Radio observations of very high energy (VHE) gamma-ray sources are fundamental to identify and reveal their nature, as well as to understand the physics behind these energetic sources. I will comment on some characteristics of extragalactic sources detected at TeV energies and radio wavelengths, and galactic sources such as gamma-ray binaries, supernova remnants (SNRs), or pulsar wind nebulae (PWNs). Special emphasis will be put on unidentified extended TeV sources, in which deep radio observations can severely constrain the proposed models and shed light on the possible sources powering the TeV emission.
