Description Although a group of galaxies is predicted to evolve into a single elliptical
galaxy within a relatively short span, no clear counterpart of such a merger
remnant has been identified with a direct evidence so far. Here we propose a 30
ksec observation of NGC1550 to attempt a first firm identification of such
remnants, through measurements of the distribution of the gas metallicity which
is assumed to reflect the distrubution of galaxies in the past.

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.
