| Description | Based on prior ROSAT observations, the supernova remnant (SNR) CTB 1 features X-ray center-filled emission within a well-defined radio shell, characteristic of ..mixed-morphology SNRs. Our ASCA and Chandra observations revealed that CTB 1 is an oxygen-rich SNR with enhanced abundances of O and Ne despite its evolved state. We also found a hard component to the X-ray emission, and our Chandra images suggest that the hard emission may be localized. Our scientific goals are i) to examine clumping structures of SN ejecta, where the ejecta are still dominant at an old age, ii) to determine if the hard emission has a non-thermal origin and is truly localized, and iii) to resolve the hard point-like source and determine if it is a pulsar-wind nebula associated with CTB 1. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
