Observation of Nonthermal Emission from the Supernova Remnant Ic 443 with Rxte
نویسنده
چکیده
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 nonthermal components. We compare these results with recent results of other X-ray missions and discuss the need for a cut-off in the nonthermal spectrum. Recent Chandra and XMM-Newton observations suggest that much of the nonthermal 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 o f the nonthermal component and its possible association with the unidentified EGRET source.

Nonthermal Emission from a Supernova Remnant in a Molecular Cloud
In evolved supernova remnants (SNRs) interacting with molecular clouds, a highly inhomogeneous structure consisting of a forward shock of moderate Mach number, a cooling layer, a dense radiative shell and an interior region filled with hot tenuous plasma is expected. We present a model of nonthermal electron injection, acceleration and propagation in that environment and find that these SNRs ar...
متن کاملXMM-Newton observations of the supernova remnant IC 443: II. evidence of stellar ejecta in the inner regions
Aims. We investigate the spatial distribution of the physical and chemical properties of the hot X-ray emitting plasma of the supernova remnant IC 443, in order to get important constraints on its ionization stage, on the progenitor supernova explosion, on the age of the remnant, and its physical association with a close pulsar wind nebula. Methods. We present XMM-Newton images of IC 443, media...
متن کاملThe plerion nebula in IC 443: the XMM-Newton view
XMM-Newton observations of the X-ray feature 1SAX J0617.1+2221 in the IC 443 supernova remnant are reported. We resolve the structure of the nebula into a compact core with a hard spectrum of photon index γ = 1.63 −0.10 in the 2–10 keV energy range. The nebula also has an extended (∼ 8 × 5) X-ray halo, much larger than the radio emission extension. The photon index softens, following a linear s...
متن کاملObservation of Extended Vhe Emission from the Supernova Remnant Ic 443 with Veritas
We present evidence that the very-high-energy (VHE, E > 100 GeV) gamma-ray emission coincident with the supernova remnant IC 443 is extended. IC 443 contains one of the best-studied sites of supernova remnant/molecular cloud interaction and the pulsar wind nebula CXOU J061705.3+222127, both of which are important targets for VHE observations. VERITAS observed IC 443 for 37.9 hours during 2007 a...
متن کاملHard X-ray emission from IC443: evidence for a shocked molecular clump?
We report BeppoSAX observations of spatially resolved hard X-ray emission from IC 443, a supernova remnant interacting with a molecular cloud. The emission is shown to come from two localized features spatially correlated with bright molecular emission regions. Both hard X-ray features have soft X-ray counterparts, in one case shifted by 20 toward the remnant interior. The spectra of X-ray emis...
