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

| 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. |
