The EGRET sky: a new interstellar emission model and source detection
Résumé
The comparison of HI, CO, dust, and gamma-ray maps in the solar neighborhood has led to the discovery of large amounts of dark gas. The large mass and angular extent of the local dark clouds, as well as their clumpiness, imply severe revisions of the interstellar emission model to high latitudes, therefore of the detectability of a point-source above the diffuse background. We have used this new model to search for point-like sources at 5\degres$\leq$|b|$ _leq$80\degres and we show that numerous persistent unidentified EGRET sources are not confirmed as significant sources.
