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 XMM and NuSTAR in combination, the detection of X-ray pulsations from a growing subset of ULXs (unambiguously confirming them as super-Eddington neutron stars) and the detection of powerful outflows from a handful of systems. NGC5055 ULX1 is an extreme ULX (L(X,peak) virgul 1e40 erg-s) that has received very little observational attention to date. Here, we proposal a deep, coordinated XMM+NuSTAR observation (130+150ks exposures, respectively) in order to constrain its broadband spectrum, search for pulsations, and atomic outflow signatures. These observations will provide the first robust constraints on the nature of this extreme binary |

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. |
