Ngc 4569, Xmm-Newton Proposal 02006501
Scientific paper
We propose the X-ray mapping of the strongly stripped Virgo Cluster spiral NGC 4569 close to which ROSAT data show a large X-ray emitting cloud. We found that this galaxy also possesses a huge (at least 20 kpc) radio halo with strong vertical magnetic fields. These features are indicative of either strong nuclear outflows (which by itself is unusual concerning its only weakly active nucleus) or the gas outflow from the whole disk as predicted by models of active stripping via the intracluster gas. In the second case we have an unique possibility to study the galaxy caught in a stripping process. Our observations will provide the key to discriminate between the mentioned hypotheses and will constrain numerical models of the gas outflows in cluster galaxies.
