Title: RESOLVING THE QUESTION OF IC443'S HARD EMISSION
Observer: KEOHANE
Subject Category: SN, SNR, and isolated NS
Seq: 500056 ObsId: 00760
Long-term Plan bin: no LTS bin
ABSTRACT
AXAF is ideally suited to investigate the hard X-ray region of the SNR IC 443, which is currently thought to be X-ray synchrotron radiation as a result of a particular interaction between a shock and a molecular cloud. Alternate explanations, such as a pulsar powered nebula, have still not been completely ruled out. This proposed observation will image the currently unresolved core of hard emission, map out the hardness ratio to arcsecond resolution and enable "sliding box" style spectral fitting which can constrain the hard X-ray spectral index within +/-0.1 with arcminute spatial resolution. This observation is a key part of a multi-wavelength observing program to investigate the synchrotron structure of this anomalous region.
