An EPIC view of absorbed HMXBs in the Scutum Arm
Abstract
Observations are proposed for 5 new unclassified gamma-ray sources in the Scutum Arm. Each source will be targeted by EPIC PN and MOS cameras for 25 ks providing us with: a refined position that will facilitate optical/IR identification; spectral characteristics including the slope of the power law in X-rays and the photoelectric absorption; and timing characteristics in the case of Galactic XRBs. The targets lie within 5degs of the plane of the Milky Way, towards the tangent to the Scutum Arm, and are expected to be Galactic in origin. The main objective is to elucidate the nature of these sources. An additional benefit is that we will have a more complete sample of high-energy emitters in the Scutum Arm to compare with absorbed HMXBs in the Norma Arm.
