Description We propose to observe the gravitationally lensed quadruple quasar Q2237+0305 with XMM with three goals in mind. The first is to determine its X-ray luminosity and hence the spectral energy distribution of this important high redshift quasar. The second goal is to detect possible variability in the X-ray flux of this quasar on time scales of a few hours or smaller. The third goal relates to the possibility of determining the nature of any X-ray variability, since it can be either intrinsic or microlens-induced. Intrinsic variability could be used to determine the time delay (which is inversely proportional to the Hubble constant), microlensing depends on the source size of the X-ray emitting region and on the possible dark compact objects in the lensing galaxy.

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.
