Description | We propose a new observation of an ULIRG IRAS F00183-7111 at z=0.33 hosting an obscured nucleus with deep silicate absorption. The early XMM observation found a large EW of Fe K line, suggesting the 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 cold obscuring matter, and subsequent observations show the line may be continuously declining. A recent NuSTAR observation suggests that cold absorption for the nucleus 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 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. |
