Abstract
We report here new results on four weak sources of hard X‐rays (≳35 keV) of the Galactic Center region, obtained from the data collected by the SIGMA/GRANAT telescope between 1990 March and 1993 April. Two of these sources are quasi‐persistent emitters of hard X‐rays: the burst source in Terzan 2 globular cluster and a new source (GRS 1743‐290) detected at ≊10’ from Sgr A*. Two others, coincident with the known X‐ray bursters A 1742‐2942 and X 1732‐304, the latter in the Terzan 1 globular cluster, are newly discovered sources of transient hard X‐ray emission.Keywords
