Observation of non-thermal emission from the supernova remnant IC 443 with RXTE

In this paper we present analysis of X-ray spectra from the supernova remnant IC 443 obtained using the PCA on RXTE. The spectra in the 3–20 keV band are well fit by a two-component model consisting of thermal and non-thermal components. We compare these results with recent results of other X-ray mi...

Description
Summary:In this paper we present analysis of X-ray spectra from the supernova remnant IC 443 obtained using the PCA on RXTE. The spectra in the 3–20 keV band are well fit by a two-component model consisting of thermal and non-thermal components. We compare these results with recent results of other X-ray missions and discuss the need for a cut-off in the non-thermal spectrum. Recent Chandra and XMM-Newton observations suggest that much of the non-thermal emission from IC 443 can be attributed to a pulsar wind nebula. We present the results of our search for periodic emission in the RXTE PCA data. We then discuss the origin of the non-thermal component and its possible association with the unidentified EGRET source.
