Abstract We propose to test galaxy formation models by characterizing the outer hotcoronae of two very massive spiral galaxies. Theoretical models predict X-rayemission (L_x>10^{40} ergs/s) at large radii around massive spiral galaxies.This emission is a fundamental prediction of current formation models thatsuccessfully predict many observed galaxy properties. We have selected twogalaxies, NGC1961 and NGC6753, that are optically luminous, undisturbed, withmoderate star formation rates, and that can be probed to sufficiently largeradii (25-50 kpc) within the large XMM FOV with 52ks and 64ks observations. Wewill derive the X-ray gas density profiles and the mean gas temperature of theextended, hot coronae for these two galaxies.

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.
