INTEGRAL detects renewed activity from IGR J19294+1816
Abstract
During recent INTEGRAL Galactic Plane Scanning observation (PI: A. Bazzano), starting 2012 may 26 at 10:38 UTC (total exposure time ~36.3 ks), IBIS/ISGRI detected renewed activity from the transient binary system IGR J19294+1816 (Atel #1997). This hard X-ray transient was detected at about 9 sigma in the IBIS map 18-40 keV, with a flux of 18+/-2 mCrab (uncertainties at 90% c.l.). Its 18-60 keV spectrum is well fitted by a power law model with photon index of 3.6(+0.8,-0.7) and reduced chi-squared of 0.97 (15 d.o.f.).
