| Abstract | The luminosity of X-ray haloes around disc galaxies is a crucial quantity forconstraining theories for the assembly of disc galaxies. We have compiled aunique, physically realistic sample of hydrodynamical simulations of disc galaxyformation and evolution, predicting present day X-ray halo luminosities and thespatial distribution of the X-ray emission. Here we propose to test these novelmodels by obtaining deep XMM-Newton pointings of two massive, nearby, edge-ondisc galaxies. A detection of X-ray haloes around these massive disc galaxieswill for the first time prove that disc formation is on-going today.Alternatively, a non-detection will require a major re-thinking of the currentlyaccepted scenario for assembling disc 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. |
