|Title||A hard X-ray view of the inner disc in Mrk 1040|
|Author||Dr James Reeves|
|Description||The study of the X-ray spectral components in AGN allows us in principle to infer the properties of the accretion disk and in some cases, the black hole spin. This proposal concerns the study of the nearby, X- ray bright Seyfert 1 galaxy, Mrk 1040, which shows the presence of an unusually intense and highly broadened (FWHM: 60000 km-s) Fe K line, as well as a strong hard X-ray excess above 10 keV. Mrk 1040 is also rapidly variable and shows a tentative detection of lags at soft X-rays. Here we request simultaneous XMM-Newton and NuSTAR observations (160 ks and 120 ks), enabling us to determine the origin of the hard X-ray excess and ultimately the spin of the central black hole. We will also determine the presence the X-ray lags above 10 keV, as expected in disc reverberation scenarios.|

|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.
