IRAS 18325-5926 is a type-2 Seyfert galaxy displaying unusual spectralproperties; namely a broad Fe line perhaps originating primarily from He-likeFe, ionised warm-absorber features and a moderately low absorption column ofcold matter. It also exhibits significant and rapid X-ray variability. However,this source has been somewhat overlooked and the only existing XMM-Newtonobservation suffered from severe technical problems. Through a new 150ksexposure with XMM-Newton we aim to constrain the true nature and origin of thebroad Fe line, confirm the presence of outflowing ionised absorption, test forsoft X-ray reflection features from an ionised accretion disc and probe thevariability of the continuum, iron line and warm absorber on both short and long timescales.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
