| Abstract | High-energy neutrinos have been recently associated with astrophysical jets.Despite many efforts the details and micro-physics of the neutrino emissionmechanism still elude us. Here we propose new observations of 10 radio bright,but gamma-ray dark, sources that were found to be positionally coincident withthe arrival directions of neutrinos. With the new XMM-Newton observations wewill confidently measure their X-ray spectrum for the first time, and constrainthe shape of their spectral energy distribution. This will allow us to confirm(or reject) them as neutrino emitters which will have significant implicationson both the location and neutrino emission mechanism in astrophysical jets aswell as our understanding of the high-energy emission processes in general |

| 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. |
