Blazar Counterparts for 3EG Sources at −40o < Decl. < 0o: Pushing South through the Bulge

Abstract

Supplementing existing survey data with VLA observations, we have extended $\gamma-$ray counterpart identifications down to decl. = -40$^\circ$ using our Figure of Merit approach. We find blazar counterparts for $\sim$ 70% of EGRET sources above decl. = -40$^\circ$ away from the Galaxy. Spectroscopic confirmation is in progress, and spectra for $\sim$ two dozen sources are presented here. We find evidence that increased exposure in the bulge region allowed EGRET to detect relatively faint blazars; a clear excess of non-blazar objects in this region however argues for an additional (new) source class.
