About this Image

XMM-Newton combined EPIC-pn & MOS contour map of NGC 4666 in the 0.5 - 0.9 keV energy band overlaid on the Hα+N[II] optical narrow band image from M. Lehnert. In the halo the most extended optical emission line filaments form an "X"-shaped structure (cf. the plates in Lehnert & Heckman (1996)). Vectors mark the orientation of the magnetic field observed at 4.89 GHz with the VLA (Dahlem et al. (1997)), their lengths are proportional to the polarized intensity.
Extra-planar soft X-ray emitting hot gas is observed above the most actively star-forming regions in the galactic disk of NGC 4666 and coexists together with filaments of the warm ionized medium, cosmic rays and vertical magnetic field structures channelling (or following) the outflow.

Investigator(s):  M. Ehle, M. Dahlem
