Fermi-LAT results on galactic plane -ray transient sources

The Large Area Telescope on the Fermi -ray Space Telescope provides unprecedented sensitivity for all-sky monitoring of -ray activity. It has detected a few Galactic sources, including 2 -ray binaries and a microquasar. In addition, it is an adequate telescope to detect other transient sources. The observatory scans the entire sky every three hours and allows a general search for aring activity on daily timescales. This search is con- ducted automatically as part of the ground processing of the data and allows a fast response to transient events, typically less than a day. Most of the outbursts detected are spatially associated with known blazars, but in several cases during the rst years of observations, -ray ares occurring near the Galactic plane did not reveal any initially compelling counterparts. This prompted follow-up observations in X-ray, optical, and radio to attempt to identify the origin of the emission and probe the possible existence of a class of transient -ray sources in the Galaxy. Here we report on these LAT events and the results of the multiwavelength counterpart searches.
