XMM-Newton and Chandra observations of diffuse-like X-ray emission from TeV J2032+4130
Abstract
TeV J2032+4130 is an unidentified source of γ-rays in the TeV energy range near the star forming region Cygnus OB2, and has been associated with discrete sources in X-rays and radio, possibly outlying members of Cygnus OB2. Many sources in the vicinity are known to exhibit flaring in X-rays. Horns et al. (2007) have found evidence based on XMM Observations for diffuse-like X-ray emission spatially coincident with the HEGRA TeV source significance contours. They concluded that this diffuse emission in the X-rays is the likely counterpart to TeV J2032+4130. If true, this may fundamentally alter the models of the origin of the γ-rays detected in the region. The intensity of their reported diffuse X-ray emission is such that it ought to have been detected in our Chandra observations. In order to resolve the situation regarding the reality of the putative diffuse emission, we report here on an independent analysis of the XMM-Newton and Chandra data.
