Abstract
The foreground component of the X-ray Background (XRB) can be studied by cross-correlating its intensity with galaxy catalogs. We computed the two-point cross-correlation function between 67 {\em Einstein} X-ray fields and the APM galaxy catalog. We detected a signal with an amplitude of , significant at the level. The reality of this signal was tested with a series of control data sets. We discuss how this signal can be used to constrain models of the XRB.
