Localization, Time Histories, and Energy Spectra of a New Type of Recurrent High-Energy Transient Source
Abstract
The authors report the detection of a recurrent high-energy transient source which is neither a classical X-ray nor a gamma-ray burster, but whose properties are intermediate between the two. The energy spectra of 12 recurrent events are found to be soft, characterized by kT's of 34 - 56 keV. The time histories are short (≤128 ms) with rise and fall times as fast as ≡10 ms. The source location is a 0.12 deg2 region about 10° from the Galactic center.
