Abstract:
To find X-ray bursts from sources within the field of view of the
IBIS/INTEGRAL telescope, we have analyzed all the archival data of the
telescope available at the time of writing the paper (the observations
from January 2003 to April 2009). We have detected 834 hard (15-25keV)
X-ray bursts, 239 of which were simultaneously recorded by the
JEM-X/INTEGRAL telescope in the standard X-ray energy range. More than
70% of all bursts (587 events) have been recorded from the well-known
X-ray burster GX 354-0. We have found upper limits on the distances to
their sources by assuming that the Eddington luminosity limit was
reached at the brightness maximum of the brightest bursts.
