Description Specific abundance patterns are left by distinct chemical enrichment processes
during the formation and evolution of galaxies. We propose to observe the
luminous infrared galaxy Arp 299 with a total exposure of 130 ks. The existing
RGS spectrum with a short exposure yields rather high Mg/O and Ne/O abundance
ratios (with large uncertainties) in the hot atmosphere of the host galaxy.
Core-collapse supernovae are the main metal factory of these elements.
Nonetheless, the observed abundance ratios are in tension with various initial
mass function weighted yields at the 1-2 sigma confidence level. Combining the
archival and proposed observations, we can accurately measure the metal
abundances. We will explore possible origins of the unusual abundance ratios.

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.
