Description The recent discovery of a handfuln of ULXs showing pulsations (PULXs)
unambiguously associated them to neutron stars (NSs) exceeding up to about 500
times their L_Edd. During AO17 we were awarded a LP aimed at searching for new
PULXs within 8 fields containing promising candidates. So far we obtained data
for half of sample and we discovered one new PULX. This result confirms the
goodness of the LP adopted strategy and that a relatively large fraction of ULXs
likely hosts an accreting NS. The present proposal is aimed at observing two
bright (high flux) ULXs in Timing mode and at looking for coherent signals over
a period range (1ms<P<100ms). The detection of even one very fast PULX would be
very important for constraining NS accretion models as well as binary systems.

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.
