A Northern Survey of Gamma-Ray Blazar Candidates (2005)
Sowards-Emmerd, David, Romani, Roger W., Michelson, Peter F., Healey, Stephen E., Nolan, Patrick L.
In preparation for GLAST, we have compiled a sample of blazar candidates to increase the pool of well studied AGN from which GLAST counterparts will be drawn. Sources were selected with our Figure of...

Q0906+6930: The Highest-Redshift Blazar (2004)
Romani, Roger W., Sowards-Emmerd, David, Greenhill, Lincoln, Michelson, Peter
We report the discovery of a radio-loud flat-spectrum QSO at z=5.47 with properties similar to those of the EGRET gamma-ray blazars. This source is the brightest radio QSO at z>5, with a pc-scale...
The Gamma-Ray Blazar Content of the Northern Sky (2002)
Sowards-Emmerd, David, Romani, Roger W., Michelson, Peter F.
Using survey data, we have re-evaluated the correlation of flat spectrum radio sources with EGRET sources in the Northern sky. A likelihood analysis incorporating the radio and X-ray properties and...
