| Description | Cocooned AGN are a new population of AGN selected with MIR properties indicative of powerful quasars, but quiescent galaxy-like optical spectra, including weak-to-absent [OIII] emission. This is likely due to AGN youth or virgul4 pi covering factor obscuring material enshrouding the AGN, but the existing minimal X-ray data has been insufficient to differentiate between these scenarios. We propose a targeted campaign of 8 of the brightest CAGN in our sample. An XMM-Newton exposure quasi-simultaneously with NuSTAR is sufficient to make this distinction, even up to Compton-thick levels of obscuration, with parameter degeneracies. These observations are essential to determine the emission mechanism responsible for the CAGN and hence push towards a complete census of black hole growth evolution. |

| 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. |
