Description A new ULX in the galaxy NGC 4045 that reaches X-ray luminosities greater than 10^41 erg s^-1 was recently found, making it one of the most powerful ULXs discovered to date. DDT observations with NuSTAR revealed enticing candidate signals of an absorption line at 8.7 keV which could be the signature of an ultrafast outflow, the hallmark of super-Eddington accretion, and a potential pulsation signal, that could confirm the source as an neutron star accretor. However, neither of these were found to be significant in the 50-ks observation. Here we propose follow-up target of opportunity observations with NuSTAR and XMM-Newton in order to confirm these signals.

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.
