| Description | We request 110ks XMM-Newton observation of the highly variable, narrow-line quasar PG1404+226. The existing short 21ks XMM-Newton observation has revealed high velocity (>=25000 km/s), variable absorption features in the 1-3keV range due to NeIX and SXVI. The absorption lines were weaker at lower flux. The primary objective is to determine the response of the high velocity warm absorbing gas to the variable continuum and put tight constraints on the density and the location of the WA gas. The long observation will also allow us to study variability of the soft excess, hard power-law and UV emission and probe relationship between them in this extreme quasar. |

| 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. |
