GRO J1744-28

Abstract:

MH Finger, Compton Observatory Science Support Center; RB Wilson and BA Harmon, Marshall Space Flight Center, NASA; K. Hagedon, University Space Research Association; and TA Prince, California Institute of Technology, report for the Compton Observatory BATSE team:" Pulsations with a period of 467 ms are being detected in the energy band 25-45 keV from a source in the galactic-center region. The pulsed flux is about 40 percent of the total flux observed from the hard x-ray transient GRO J1744-28 (IAUC 6284). Absence of any other persistent source consistent with the direction and flux of the observed pulsed emission implies that the pulsations are from GRO J1744-28. The 31-ms-resolution data in which the pulsations were observed excluded time intervals containing outbursts from the possibly separate burst source in the same region (IAUC 6272, 6275, 6276). On Jan. 6.0 UT, the measured …
