Abstract

We present a preliminary analysis of XMM-Newton observations of the oxygen-rich supernova remnant G292.0+1.8 (MSH 11-54). Although the spatial extent of the remnant is 8 arcmin the bright central bar is narrow (1'-2') resulting in RGS spectra of a high spectral quality. This allows us to spectroscopically identify a cool, Te = 0.3 keV, and underionized component, resolve details of the Fe-L complex, and resolve the forbidden and resonant lines of the O VII triplet. We are also able to constrain the kinematics of the remnant using Ne IX as observed in the second order spectrum, and O VIII in the first order spectrum. We do not find evidence for O VII line shifts or Doppler broadening (sigma_v < 731 km/s), but line broadening of the Ne X Ly-alpha line seems to be present, corresponding to sigma_v ~ 1500 km/s.
