| Description | NGC 3227 has it all: rapid X-ray variability, a negative lag, variable Fe K emission and variable absorption. However, no observing campaign to date has been constructed to optimally use the timing and spectroscopic signatures of the reprocessor together to map the X-ray gas. We propose to combine 320 ks on XMM and 160 ks on Nustar to isolate reverberation signatures from the circumnuclear gas. Our proposed methodology will allow us to measure directly in the light curve the actual reverberation delay, the timescale of the delay and the shape of the "transfer function", which give an unambiguous model independent constraints on the reverberating gas. This gas is key to understanding the accretion process and the co-evolution of galaxies and their nuclear black holes. |

| 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. |
