Investigating the X-ray halo in the nearby edge-on galaxy NGC5775

It is proposed to observe the Xray emission of the edgeon galaxy NGC5775,known to possess an extended diffuse ionized gas halo and a radio continuum halo, in order to search for an associated hot phase of the ISM in the halo.Since models of the ISM describe the presence of halo gas in the context of alarge scale transport of matter from the disk into the halo, which is driven bythe star formation in the underlying disk, the presence of DIG in the halo is avery good indicator for such a process in action. The spatial distribution andspectral information of the halo gas obtained with XMM will allow us to answersome important questions with regard to the transport mechanisms and energeticsof the diskhalo connection. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
