| Abstract | One of the biggest challenges in modern radio astronomy is understanding whatcauses the Fanaroff-Riley morphological dichotomy in powerful radio galaxies(FR-I/II). PKS2250-351 (z=0.2115) is a rare example of a hybrid morphologysource (HyMoRS), with an FR-II hotspot and an FR-I jet and lobe on either side.PKS 2250-351 is located within the rich Abell 3936 galaxy cluster. We proposeXMM-Newton observations to unveil the temperature, luminosity and substructureof Abell 3936. These first even X-ray observations of the large scaleenvironment around a HyMoRS are uniquely positioned to test whether the FR-I/IIdichotomy is caused by interaction between the jets of PKS2250-351 with anoverdense, asymmetric environment and will yield crucial insights into jet launching in black holes. |

| 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. |
