Abstract | This joint Chandra/XMM-Newton mosaic of the massive star-forming region Westerhout 4 (W4) in the perseus Arm chronicles the X-ray output of all aspects of high-mass stars: wind shocks near the stellar surface, wind-wind and wind-cloud shocks on parsec scales, triggered star formation, superbubbles, and chimneys. This study focusses on the feedback of the W4 complex on theinterestellar medium, where stellar winds from the massive young cluster IC 1805 are re-energizing the famous W4 superbubble that triggered star formation in the adjacent W3 giant molecular cloud. W4 is the best Galacticexample of the superbubble phenomenon and provides direct evidence that massive stellar clusters have profound influence on galactic halos. |

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. |
