| Abstract | PG 1126-041 is a low redshift BAL QSO which shows strong X-ray variability both in flux and spectral shape, on timescales of both years and hours. Previous X-ray observations, though limited in S/N, strongly suggest variablewarm absorption as the cause of the observed spectral variability. A long andcontinuous XMM-Newton observation of PG 1126-041 will allow us to accuratelymeasure physical parameters, and their variations with time, like intrinsiccontinuum luminosity and photon index, warm absorber column density, ionizationparameter, covering fraction, and the physical link among them. The combination of the presence of a clear and powerful UV outflow with the variability of theX-ray warm absorber makes PG~1126-041 a unique case study for quasar outflows. |

| 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. |
