| Abstract | We propose a new observation of an ULIRG IRAS F00183-7111 at z=0.33 hosting an obscured nucleus with deep silicateabsorption. The early XMM observation found a large EW of Fe K line, suggestingthe observed X-ray emission to be reflected light from a Compton thick AGN.However, the line energy (6.7 keV) indicates that it originates from highly ionized gas instead of coldobscuring matter, and subsequent observations show the line may be continuouslydeclining. A recent NuSTAR observation suggests that cold absorption for thenucleus is moderate and an additional highly-ionized absorber, possibly linked to the galaxy s outflow features, may be present. We request a 80 ks XMM-Newton observation to test the line variability and probe the high-ionization gas of this extreme active nucleus. |

| 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. |
