| Abstract | We propose a joint NuSTAR/XMM monitoring of the high accretion rate Seyfert 1 HE1143-1810 (L/Ledd>0.5), consisting of 5x20 ks observations spaced by 2-3 days.The source is an ideal candidate to obtain high sensitivity measurements over abroad (UV/hard X-rays) high-energy spectrum, which will allow us to: 1) studythe UV/X-ray spectrum with the highest possible accuracy and test physicallymotivated Comptonization models, 2) investigate the nature of the soft X-rayexcess, and 3) put firm conclusions on the reflection component. Theseobservations will allow for a direct comparison with different sources, inparticular with a similar, successful NuSTAR/XMM monitoring of NGC 4593(L/Ledd<0.15). |

| 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. |
