Title Revisiting the obscuring wind of NGC 5548

Description An obscuring wind featuring heavy absorption of the soft X-ray continuum associated with blue-shifted UV broad absorption lines was previously discovered in NGC 5548. The obscurer has been present in our line-of-sight (LOS) since at least 2011. Outside our LOS, if photons from the central engine to the narrow-line region are also screened, X-ray narrow emission lines would be diminished, given adequate delay time. We propose to observe NGC 5548 with XMM- Newton for 70 ks, we can verify whether the narrow emission lines in the soft X-ray band are diminished. This helps us to better understand the geometry of the obscurer. With coordinated HST-COS, we can study the FUV and NUV absorption lines associated with the obscurer along the LOS.

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.
