| Description | The ultraluminous X-ray source population is now broadly expected to be dominated by super-Eddington accretors, thanks to the broadband spectroscopy provided by NuSTAR and XMM-Newton in combination, and the detection of X-ray pulsations from a growing subset of ULXs (unambiguously confirming them as super-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 observational attention to date. Here, we propose coordinated 100+50 ks NuSTAR+XMM-Newton observations of these sources in order to constrain their broadband spectra and search for pulsations. These observations will provide the first robust constraints on the nature of these two extreme 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. |
