| Abstract | Mrk 1044 is one of the brightest super-Eddington NLS1s in X-rays, being 30-100times brighter than 1H 0707-495 above 2 keV. It offers an ideal laboratory todetermine the geometry of the accretion disc from the Fourier variabilitytechniques to measure multi-wavelength time lags. We propose a large program ofsimultaneous XMM-Newton and NuSTAR observations, in order to apply spectral-timing techniques across the entire UV to 50 keV bandpass. This should enable usto distinguish between a lamppost geometry, with a compact source close to theevent horizon illuminating a flat disc, and a wind geometry, where an extendedsource reflects from a puffed up inner disc. Existing XMM-Newton and NuSTAR dataare non-simultaneous, and are limited by short exposures and background flaring. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
