ESO 141-G55 is a nearby, very X-ray bright, BLS1, with little or nointervening X-ray neutral/warm absorption. As such, it is a perfect AGNfor a clean, unimpeded view into the innermost core of the nucleus: thedisc-corona system. We propose its first simultaneous NuSTAR (110 ks)and XMM-Newton (110 ks) observation. This joint broad-band campaignwill provide an unprecedented, comprehensive view of this AGN: probingits disc-corona characteristics, its SMBH spin, and its spectral energydistribution.

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.
