TL;DR: In this paper, the authors presented the results concerning the nature of 33 high-energy objects with the use of six telescopes of different sizes and from one on-line archive, which indicated that the majority of these objects (23 out of 33) are active galactic nuclei (AGNs), whereas 10 are sources in the local Universe with eight of which in the Galaxy and two in the Small Magellanic Cloud (SMC).
