| Abstract | The ultraluminous X-ray source population is now broadly expected to bedominated by super-Eddington accretors, thanks to the broadband spectroscopyprovided by NuSTAR and XMM-Newton in combination, and the detection of X-raypulsations from a growing subset of ULXs (unambiguously confirming them assuper-Eddington neutron stars). IC 5052 ULX and ESO 501-023 ULX are extreme ULXs(LX;peak > 1040 erg so???1) that have received very little observationalattention to date. Here, we propose coordinated 100+50 ks NuSTAR+XMM-Newtonobservations of these sources in order to constrain their broadband spectra andsearch for pulsations. These observations will provide the first robustconstraints on the nature of these two extreme binary systems. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
