|Title||Is the Relativistic Fe K Line in the High-Luminosity Quasar RBS 1423 Persistent?|
|Author||Dr Tahir Yaqoob|
|Description||RBS 1423 is one of only a few high-luminosity QSO with a relativistically broadened Fe K line, which was found by Krumpe et al. (2007) from a 20 ks XMM observation. The QSO is an important case study for probing the inner accretion disk and strong gravity regime in high-luminosity QSO, and potentially the black-hole spin. We propose another XMM 20 ks snapshot to investigate if the Fe K line is persistent or variable. This will help to strategize future longer follow-ups since a varaiable line would benefit from a monitoring program, whereas a deep exposure to better constrain the accretion disk and black-hole spin would be more appropriate for a persistent line.|

|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.
