| Description | We propose to observe the NLS1 PG 1402+261 (at z=0.164). A short 9ks observation revealed an unusually strong (EW=2keV) and very broad Fe K emission line. The line centroid energy at 7.3 keV appears blue-shifted with respect to the Fe Ka band, while the blue-wing of the line extends to 9 keV. The line profile can be fitted with reflection from a disk around a Kerr black hole, but requires an inclination in excess of 60 degrees, inconsistent with AGN unified models. Alternatively the spectrum may be explained by a large column density, high ionization absorber from a powerful outflow. We propose for 2x50ks XMM-Newton observations to distinguish between the disk reflection and outflow 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. |
