| Description | X-ray QPO in AGN has timescales of hours or much longer. These timescales, coupled with the requirement to see > 10 cycles to have a significant detection, means that these are challenging to detect. So far the most robust AGN QPO was found in an XMM-Newton observation of RE J1034+396 in 2007. Subsequent observations showed that the QPO is transient, emerging only in around half of the datasets. There was no XMM-Newton observations since 2011 due to the limited visibility, but this will recover to up to 80 ks from 2018. We propose to revisit it with both XMM-Newton and NuSTAR, in order to investigate its QPO 7 years after the last observation and obtain a deeper understanding of its X-ray emission. |

| 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. |
