1996A&AS..120C.137Z Deep search for celestial hard X-ray emission by earth occultation with BATSE/CGRO. Zhang S.N., Harmon B.A., Paciesas W.S., Fishman G.J. Universities Space Research Association, Huntsville, AL 35806, U. S. A. NASA/Marshall Space Flight Center, ES-84, Huntsville, Al 35812, U. S. A. Received November 15, 1995; accepted January 21, 1996 Abstract. As an important part of the BATSE/CGRO's Cycle 4 guest investigation effort, the BATSE team, in close collaboration with several guest investigators, have started a program to search for weak persistent emission (<~5mCrab) and transient events (<~30mCrab) from several classes of high energy astrophysical objects which were not previously detected by BATSE, including Seyfert II galaxies, X-ray binary neutron star systems (pulsars and X-ray bursters), black hole candidates and unidentified EGRET and COS-B sources. Earth occultation, occultation transform imaging and epoch folding techniques are used in this search effort. Preliminary results have shown positive detections from sources in most of the above listed classes. The search program and the preliminary results are briefly summarised in this paper.
