Description The two very-luminous ULXs (L[X] greater than 2E39 erg/s) in NGC 1672 are
positioned precisely at the ends of the nuclear bar. The most luminous ULXs are
the most difficult to explain as .normal. X-ray binaries, and so are likely ULX
candidates for IMBHs. We propose a detailed study, for the first time, of the
X-ray spectra of these two fascinating ULXs, to study their spectral features
and compare with ULX model predictions. A comparison with XMM-Newton X-ray
spectra of ULXs in non-barred spirals will allow an important test to see if
ULXs in spiral bars have unique spectral properties.

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.
