The nature of discrete sources contributing to the extragalactic X-ray background (XRB) in the energy range ∼0.1-3 keV has been investigated via optical identifications based on positional coincidence and spectroscopy. The results presented here ad

We discuss 20 X-ray sources in the NRL HEAO-1 catalog which we identify with bright, hard X-ray emitting BL Lac objects. We discuss the definition and process of identification of these objects. We deduce limits to the surface density of > 0.0007 deg

We report on the identifications of 15 new X-ray selected Active Galactic Nuclei (AGN). The AGN have been discovered during an ongoing program to identify and study the optical counterparts of X-ray sources detected by the HEAO-1 satellite. The new A

The nature of discrete x-ray sources contributing to the all-sky x-ray background has been investigated. X-ray selected quasars account directly for ~ 30% of the all-sky x- ray background in the energy range of the Einstein Observatory. Quasars which

Two 16th magnitude BL Lac objects, H1101 - 232 and H1426 + 428, have been discovered. Each is a persistent and relatively bright X-ray source. A 2.7 percent linear polarization is measured in the optical emission or H101 - 232. The X-ray identificati
