| Description | While future soft X-ray (0.5--2 keV) surveys are being designed to discover high-redshift (z > 9) heavy-seed mass black holes (hsBHs) with M BH virgul 10^5 M SUN, a rest-frame hard X-ray spectral model is crucial to understand how many hsBHs can be detected. Motivated by this, we propose a simultaneous 70-ksec NuSTAR and 20-ksec XMM-Newton observation to a local AGN in POX 52 with M BH virgul 3x10^5 M SUN and L 2-10 virgul 10^42 erg s^-1, resembling the future targets. While there are two expected X-ray models: (1) a power-law with low-energy cutoff like ultra-luminous X-ray sources and (2) one with high-energy cutoff and reflected emission like Seyfert galaxies, the superior sensitivity of NuSTAR above 10 keV will distinguish them and provide a reliable hard X-ray spectral template. |

| 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. |
