| Abstract | The supernova remnant (SNR) G330.2+1.0 has been recently identified as anonthermal shell-type SNR in X-rays. Using our Chandra data, we found that thenonthermal X-ray emission of G330.2+1.0 originates primarily from a thincircumferential shell, and discovered a central compact object (CCO) in thisSNR. Based on our Chandra results, we propose a 70 ks follow-up XMM observationof this SNR and CCO. Our primary goal is to search for pulsations from the CCO,including a test for the period suggested by Chandra, but only with a marginalsignificance. The high time resolution and high sensitivity XMM observations areessential to search for the CCO period. We will also perform a spectral analysisof the CCO and SNR, utilizing good photon statisics obtained with XMM. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
