XMM-Newton Observations of the Supernova Remnant G299.2-2.9
Abstract
G299.2-2.9 is a 15 arcmin diameter shell-type supernova remnant (SNR) in our Galaxy which was discovered in the ROSAT all-sky survey and later confirmed as such by radio and optical observations. The X-ray emitting area of the remnant is resolved into several distinct regions: an almost complete ring interrupted only by a blow-out similar to the one seen in Cas-A, a brightened center, an enhanced knot-like region on the northeastern edge of the ring and diffuse emission extending far beyond the ring both to the northeast and to the south. The EPIC PN spectra demonstrate that the emission is thermal with surprisingly bright Si-K lines, the equivalent width of which changes significantly from place to place. The analysis of the spectra will be presented and discussed.
