|Title||Redshifted Fe emission and the measure of the BH mass in ESO 198-G24|
|Author||Dr Giovanni Miniutti|
|Description||ESO 198-G24 has a peculiar Fe line complex comprising a 6.4 keV emission line with variable profile. In addition, a narrow emission line component at lower energy has also been detected in the two XMM-Newton observations (at 5.7 keV and 5.9 keV respectively). The study of the variability of the two emission features in a long XMM--Newton observation will constrain their origin and potentially provides the possibility of studying in detail the strong field regime of General Relativity. If the redshifted feature will turn out to originate in an orbiting spot, we will be able to give the first X--ray estimate of the black hole mass in ESO 198-G24, as recently done by Iwasawa et al (2004) for NGC 3516.|

|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.
