Scientific paper

An AO-2 ACIS-I observation of Kes 79 has yielded some unexpected results, including a central point source with AXP-like spectrum and many filaments possibly caused by shock-cloud interaction. We propose a 40 ksec ACIS-I observation to a similar SNR to Kes 79: Kes 27. Kes 27 is a thermal composite SNR with a number of unusual properties: one of the youngest thermal composites, the least swept-up mass, limb-brightening at the east and a hard tail above 5 keV. Two point sources revealed by ROSAT inside the remnant can be candidates for a central pulsar. With the proposed observation, we will be able to identify an interior pulsar with any associated nebula, resolve fine structures like filaments, understand its center-filled morphology, and locate the hard tail.
