| Description | We propose a 30ks XMM-Newton observation of the tidal interaction region between the galaxies M 81 and NGC 3077. This region contains an overdensity of X-ray sources (Bi, Arp, and Zimmermann 1994) in and around the HI bridge between the galaxies. Our observation will 1) determine whether these sources are indeed associated with the M 81 system, 2) examine the physical nature of the sources (e.g. distinguish XRBs from SNRs), and 3) study differences in the X-ray populations of the tidal debris region and NGC 3077, and how this relates to the star formation history of the M 81 system. We also request a 10ks Chandra HRC observation in order to obtain sub-arcsecond astrometry for the X-ray sources, which will allow us to search for optical counterparts. |

| 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. |
