Abstract | We propose to obtain HST/COS spectra of the Seyfert 1 galaxy NGC 5548 with 9orbits in conjunction with 60 ks of XMM-Newton time. Our observations willmeasure absolute abundances anchored by accurate H I column densities for boththe narrow and broad UV absorption lines. These will add fidelity to ourmeasurements of the outflowing mass flux and kinetic energy obtained in our 2013campaign using XMM-Newton and COS, and solve discrepancies between the UV and X-ray absorbers in NGC 5548. Due to the profound influence of the new soft X-rayobscurer in NGC 5548 discovered during our 2013 campaign, simultaneous X-rayspectra are essential for determining the ionizing spectral energy distribution. |

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. |
