1000 of these sources, however, remains a mystery; these are the so-called unassociated gamma-ray sources, with no known astrophysical counterpart at any other wavelength. While many LAT unassociated sources likely belong to known classes of objects (e.g. pulsars), a more exotic origin for some of these sources is also possible (e.g. dark matter annihilation). ... These results will aid further studies and follow-up observations of LAT unassociated sources. ...
