We present timing , spectral , and long-term temporal analysis of the high mass X-ray binary ( HMXB ) 4U 1036–56 using INTEGRAL and Swift observations .
We show that it is a weak hard X-ray source spending a major fraction of the time in quiescence , and only occasionally characterized by X-ray outbursts .
The outburst activity we report here lasts several days , with a dynamic range spanned by the luminosity in quiescence and in outburst as high as \sim 30 .
We report the detection of pulse period at 854.75 \pm 4.39 s during an outburst , which is consistent with previous measurements .
Finally , we analyze the possibility of 4U 1036–56 ’ s association with the unidentified transient \gamma -ray sources AGL J1037–5708 \& GRO J1036–55 , as prompted by its positional correlation .
