Description Recent studies have found that a large fraction of LMXBs within elliptical galaxies reside within globular clusters, prompting claims that all LMXBs are formed within globular clusters. If so, the total X-ray luminosity emanating from LMXBs should scale directly with the globular cluster specific frequency, S_N. Conversely, if there is a significant field-born population of LMXBs this relation will be flatter. We have begun a program to test this claim, but we need to observe galaxies with high values of S_N to confirm our findings. We propose observations of NGC4278 (S_N=8.7) and NGC4526 (S_N=7.7), two nearby gas-poor galaxies with high well-constrained values of S_N. These observations will put stringent constraints on the field-born population of LMXBs in 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.
