Description X-ray reprocessing signatures appear in the timing and spectral characteristics
of AGN. Especially valuable is the direct measurement of the reverberation delay
of the reprocessor in response to X-ray continuum variations: extraction of the
shape of the transfer function gives the location and extent of the
circumnuclear gas. This is only possible in long observations of rapidly
variable, bright AGN. To this end, we request a 300 ks NuSTAR exposure with 160
ks of XMM data, comprising the first joint observation of NGC 4051. NuSTAR opens
up the critical window above 10 keV that is dominated by the undiluted light
echo from the X-ray reprocessor. The proposed campaign will allow us to directly
map the reverberating gas close to the black hole.

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.
