|Title||Do hybrid morphology radio sources form in a lopsided distribution of cold gas?|
|Author||Dr Brendan Miller|
|Description||We test the hypothesis that hybrid morphology radio sources (HYMORS; Gopal-Krishna & Wiita 2000) feature one-sided jet disruption caused by propagation into a large-scale overdensity of cold gas, through XMM-Newton observations of B2 1404+25A and B2 1345+28 (33 and 16 ks, respectively). These HYMORS are intrinsic low-inclination RLQs for which the X-ray spectra would ordinarily be unabsorbed. VLBA mapping places the FRI jet on the near side in B2 1404+25A, and so the putative disrupting medium can be directly detected as absorption against the core; in contrast, the FRII lobe is closer in B2 1345+28, and so a simple power-law X-ray spectrum is anticipated. Distinct results are predicted for alternative scenarios of HYMORS formation.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
