Abstract | Galaxy merger models predict rapid black hole growth and strong outflows late inthe merger as the accretion rate increases. PKS1549-79 is a powerful, lowredshift active galaxy which has undergone a recent merger. It is therefore anideal object to test our understanding of galaxy activity and mergers and forstudying feedback between AGN and their host galaxies. We propose a 75 ksecXMM-Newton observation to: (i) determine the amount and onisation state of thenuclear obscuring material in PKS1549-79 and hence confirm its status as a localproto-quasar; (ii) search for the massive, probably highly ionised, outflowingwind predicted by galaxy evolution models and hence complete a census of outflowcomponents in this object; and (iii) quantify the starburst activity. |

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. |
