Here we propose a simultaneous NuSTAR and XMM-Newton (100+50ks) observation ofIRAS 18325-5926, a highly variable type-2 Seyfert galaxy and one of the very fewwith a claim of a broad FeK profile. Archival data have previously beeninsufficient to distinguish between a relativistically broadened Fe line and ablend of narrow Gaussians. However, we will be able to break the degeneracythanks to the uninterrupted coverage of the NuSTAR bandpass extending well>10keV. Additionally, this source shows one of the clearest low-frequencylag-energy spectra to date with lags well defined up to 10keV. With NuSTAR wewill extend our lag analysis up to >50keV, providing some of the most robusttests of Fourier-based inter-band time lag models to date.

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.
