Abstract

SLX 1735-269 is among the 10 persistent, high energy, SIGMA sources which contribute significantly to the last five year averaged γ/X-ray emission from the direction of the Galactic Center. Detailed study of the source has only been carried out recently from data collected by SIGMA in the 35-150keV range without successfully establishing the nature of SLX 1735-269, consequently observations with ASCA from 0.6-10keV were performed with the aim of determining the nature of this source. The spectrum of SLX 1735-269 can be described by a powerlaw-absorber model, of photon index ~-2. No period was determined from the data by epoch folding in the range 10 to 1000 s nor from a power spectrum analysis in the range 125ms to 64s and upper limits to pulsation are derived. Yet the nature of SLX 1735-269 remains to be determined.
