Scientific paper

We propose to reobserve NGC7090, after most of the originally scheduled time was lost to high radiation background. Preliminary results of 7.1 ks of observations indicate the presence of extended soft X-ray emission in its halo, south of the nuclear area, an indication that NGC7090 is a suitable target for studies of gaseous halos. Deeper observations will allow us to perform EPIC imaging and spectroscopy to tell, as part of a multi-wavelength observing campaign, whether the 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 SF rates. All are expected to have X-ray halos associated with other tracers of extraplanar gas, such as synchrotron radio continuum and Halpha line emission.
