| Abstract | Abell 168 is a low-mass cluster with a global temperature of 2 keV. It is at thelate stage of a merger in the plane of the sky along the north-south directions.A recent GMRT and JVLA study has shown that it contains an iconic radio relic inthe north direction.The location of the radio relic it is at the very edge of the existingXMM-Newton EPIC field (12 arcmin off-axis).We have detected a potential surface brightness discontinuity exactly at thelocation of the radio relicbut we are unable to constrain its temperature. We propose an XMM observation,focusing on the radio relic, to confirm the surface brightness edge and to constrain its temperature. |

| 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. |
