We propose a deep XMM-Newton observation of the peculiar and nearby young radiogalaxy PKS 1718-649 to investigate the possibility of an accretion-disk wind.This unique case provides high chances to observe and study in detail the firstwind outflow in a jetted AGN at its early evolutionary stage. We base ourproposal on two previous low-exposure XMM-Newton observations that we acquiredin AO16/17. We find barely significant blueshifted features of highly ionizedH/He- like iron around 7-8 keV. Due to the low flux of this system, only adeeper observation can constrain the nature and parameters of a potentialoutflow in PKS 1718-649.

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.
