| Abstract | Observations of the fossil X-ray jet from the black hole transient 4U 1755-33enabled us to detect the flux decay of the southern jet, identify the X-rayemission mechanism as synchrotron radiation, and place constraints on theenergetics of the jet. We propose for a third observation with the goals ofdetecting decay in the northern jet, more accurately measuring the southern jetdecay, and searching for motions within the jet. Detection of decay of thenorthern jet at a rate similar to the southern jet would imply that the kineticpower of the jet was comparable to the X-ray luminosity while the source wasactive. We also propose observations of two additional sources likely to exhibitfossil X-ray jets. |

| 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. |
