Abstract | We propose the X-ray mapping of the strongly stripped Virgo Cluster spiral NGC4569 close to which ROSAT data show a large X-ray emitting cloud. We found thatthis galaxy also possesses a huge (at least 20 kpc) radio halo with strongvertical magnetic fields. These features are indicative of either strong nuclearoutflows (which by itself is unusual concerning its only weakly active nucleus)or the gas outflow from the whole disk as predicted by models of activestripping via the intracluster gas. In the second case we have an uniquepossibility to study the galaxy caught in a stripping process. Our observationswill provide the key to discriminate between the mentioned hypotheses and willconstrain numerical models of the gas outflows in cluster galaxies. |

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. |
