| Description | Defining scaling relationships in accreting black holes of different mass and accretion rate is the crucial step in understanding the underlying physical processes. Measuring parameters for objects with extreme mass or accretion rate has the greatest value. Here we propose a 2-orbit observation of by far the brightest very low mass AGN, NGC7314. We aim to determine: 1) whether negative high frequency spectral lags (observational diagnostic of strong gravity) scale linearly with mass, as expected from disc reflection models 2) whether PSD bend timescales depend on accretion rate or not and 3) whether the high frequency part of the PSD provides a mass indicator 4) whether lag value depends on absorption, as required in wind models for lags. |

| 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. |
