Abstract | We request 110ks XMM-Newton observation of the highly variable, narrow-linequasar PG1404+226. The existing short 21ks XMM-Newton observation has revealedhigh velocity (>=25000 km/s), variable absorption features in the 1-3keV rangedue to NeIX and SXVI. The absorption lines were weaker at lower flux. Theprimary objective is to determine the response of the high velocity warmabsorbing gas to the variable continuum and put tight constraints on the densityand the location of the WA gas. The long observation will also allow us to studyvariability of the soft excess, hard power-law and UV emission and proberelationship between them in this extreme quasar. |

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. |
