Abstract A considerable fraction of the cataloged gamma-ray sources observed with the Large Area Telescope (LAT) aboard the Fermi Gamma-ray Space Telescope are either blazar candidates of uncertain type (BCUs) or unknown sources (UGS) which have no obvious counterparts at other wavelengths. With the goal of unveiling the nature of these classes of gamma-sources, we propose a multifaceted research project involving optical observations as well as simulations assessing the capabilities of future optical telescopes. The PhD work will consist of the following phases: (i) perform simulations of UGS optical variability to assess the viability of using LSST as an identification machine of gamma-sources; (ii) high-cadence optical monitoring of UGS using the T80 telescope to identify the optical nature of UGS; and (iii) an optical spectroscopic campaign to observe the optical counterparts of BCUs and confirm their blazar nature.
