Abstract

A good fraction of Very High Energy (VHE) sources do not have confirmed counterparts at any of the other branches of the electromagnetic spectrum. In the extragalactic sky, most of those sources with counterparts are Blazars, a sub-class of AGN. However, VHE sources with identified counterparts in our Galaxy do have a wide range of categories, ranging such as supernovae remnants, pulsar wind nebulae, microquasars, etc. And other scenarios involving stars at different stages have been modeled. We carried out a deep two-band radio survey with the Giant Metrowave Radio Telescope of a large region very rich on stellar sources to assess whether additional types of known sources can be associated to the ones unidentified at high energies.
