Description | Through our survey of all serendipitous sources detected with NuSTAR, we have found one source (J1506) which stands out in having the most extreme hard X-ray spectrum. The existing data suggest that J1506 is a Compton-thick (CT) AGN. There is currently a sparsity of such discoveries in the NuSTAR extragalactic surveys. In determining the nature of J1506 we are limited by: (1) the shallow depth of the off-axis (10.8ks) NuSTAR coverage; and (2) the lack of sensitive soft X-ray (<8keV) coverage. Here, we propose a deeper and broader-energy investigation using on-axis NuSTAR and XMM observations of 60ks and 30ks duration. These will dramatically improve the broad-band (virgul0.5-50keV) spectral constraints, detect iron line emission, and place stringent constraints on a merging companion 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. |
