Title Dependence of gaseous halo properties on star formation activity in NGC 7090

Description 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.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
