%0 Journal Article %T X-ray Observations of Young Supernova Remnants %A Una Hwang %J Physics %D 2001 %I arXiv %R 10.1063/1.1377085 %X This brief review of recent X-ray observations of young supernova remnants highlights results obtained by the Chandra and XMM Newton Observatories since their launch last year. Their impressive capabilities are illustrated by results for spectral imaging, and for spatially resolved spectroscopy that isolates emission from individual ejecta knots and from the forward shock. I also review X-ray dynamical studies of supernova remnants, which should undergo significant advances during this new era. %U http://arxiv.org/abs/astro-ph/0102129v1
