| Description | What dictates the formation of luminous black hole (BH) versus neutron star (NS) X-ray binaries (XRBs)? Recent studies have shown that some ultraluminous X-ray sources in starburst and high specific star formation rate (sSFR) galaxies are pulsars, while low sSFR galaxies such as M31 have a dearth of accreting BHs. These discoveries have challenged our understanding of XRB evolution and the associated accretion processes. We request a 420 ks NuSTAR observation simultaneous with a 50 ks XMM-Newton observation of the starburst galaxy NGC 6946 (The Fireworks Galaxy) to characterize the accreting BH and NS populations and investigate the black hole fraction at luminosities below the NS Eddington limit. |

| 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. |
