| Description | We request a 90ks simultaneous XMM-Newton/NuSTAR observation of NGC7582 in order to quantify the Compton reflection and absorption variability. Previous measurements of the exceptionally strong reflection features have suffered from lack of high-quality data above 10 keV, preventing robust comparisons between observations. Additionally, NGC7582 has undergone recent spectral changes which could be due to a decrease in the average luminosity of the source or increased obscuration. Thus far, X-ray spectral investigations have been unable to fully break the degeneracy between these two models, however monitoring of the variability of the spectral components will help to distinguish which scenario best describes the geometry of circumnuclear material in this source. |

| 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. |
