| Description | We have observed the INTEGRAL/BAT NLS1 galaxy SWIFT J2127.4+5654 with Suzaku in 2007. Our observation revealed the unambigous presence of a broad iron (Fe) line from the accretion disc in this very bright source. The Suzaku observation allowed us to measure via Fe line diagnostics a black hole spin avirgul0.6. However, constraints are not yet very precise and, with the proposed observation, we aim at entering the precision era for BH spin measuremments. Moreover, tentative line profile was observed during the Suzaku observation. Our proposed 130virgulks exposure with XMM-Newton will be used to reveal the line variability and its response (or lack of it) to the continuum variation. |

| 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. |
