Description
The 6-year *Fermi* data set contains some 8000 extragalactic events with E > 100GeV. To search fo the sources of these events, we applied a clustering algorithm (DBSCAN), using a search radius based on the *Fermi*-LAT point spread function, to events from > 10 degrees above and below the Galactic plane. This analysis revealed 49 significant clusters. Of these, 21 correspond to known Very High Energy (VHE) emitting Active Galactic Nuclei (AGN) in the TeVCat catalogue and 9 represent new VHE sources – 6 BL-Lacs, one blazar of unknown type and two unidentified sources. These objects are compared with the known VHE AGN population and the prospects for follow-up observations with ground based $\gamma$-ray observatories are considered.
