| Abstract | Abell 194 is poor irregular cluster well known as linear cluster. In the centerof that cluster (r < 4), there are two bright galaxies with twin jet lobe andnarrow-angle tail, respectively. ASCA observation revealed the deficits ofX-ray surface brightness in the radio lobe and spectral hardening in the centerof the cluster. However, the moderate anglar resolution of ASCA prevented usfrom resolving the radio lobe - ICM interaction. XMM-Newton is suitable toresolve the central region and to measure the accurate physical condition of thegas in and around the radio lobe with good statistics. This observation providesus a clue to generalize the variety of morphology of radio galaxies in clusters. |

| 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. |
