Title X-ray Study of Ultraluminous X-ray Sources with XMM-Newton and NuSTAR


DOI 10.5270/esa-8k4ssoz
Author Prof Fiona Harrison
Description We propose to continue the simultaneous XMM+NuSTAR observing program for ultraluminous X-ray sources (ULXs) initiated in the previous observing cycle, with observations of two further sources of interest, Holmberg II X-1 and NGC5907 ULX. The bright X-ray emission from ULX binaries greatly exceeds the Eddington luminosity for a spherically accreting stellar-mass compact object, and understanding why this is so is one of the biggest mysteries in high energy astrophysics. Combined, XMM-Newton and NuSTAR will obtain high-quality spectra and timing measurements from 0.3 30 keV, providing powerful probes for understanding the accretion modes and nature of the central BHs.

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.
