Description We propose a joint NuSTAR and XMM observation of NGC4631 (d=7Mpc), a nearby metal-poor galaxy (Z-Z sun virgul 0.2) with multiple luminous HMXBs. We will (1) examine the nature and accretion states of the HMXBs via color diagnostics, (2) measure the galaxy-integrated 0.3-30 keV spectrum to calibrate the bolometric correction for low metallicity galaxies, and (3) investigate the contribution of each bright source to this spectrum. As an ancillary science goal, we will search for the signature of inverse Compton emission from electrons accelerated in the magnetic field of the galaxy.

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.
