Abstract We propose to reobserve NGC7090, after most of the originally scheduled time waslost to high radiation background. Preliminary results of 7.1 ks of observationsindicate the presence of extended soft X-ray emission in its halo, south of thenuclear area, an indication that NGC7090 is a suitable target for studies ofgaseous halos. Deeper observations will allow us to perform EPIC imaging andspectroscopy to tell, as part of a multi-wavelength observing campaign, whetherthe halo of the low-mass spiral NGC7090 with a moderate level of star formation(SF) is different from those of other, more massive spirals with higher SFrates. All are expected to have X-ray halos associated with other tracers ofextraplanar gas, such as synchrotron radio continuum and Halpha line emission.

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.
