Description
Abell168 is a low-mass cluster with a global temperature of 2 keV. It is at the late stage of a
merger in the plane of the sky along the north-south directions. Chandra observations have
revealed prominent cold fronts along the merging axis. A recent GMRT and JVLA study has
shown that it contains an iconic radio relic in the north direction, preceding the bright cold
front. The location of the radio relic falls out of the field of view of the Chandra
observations. We have detected a promising surface brightness discontinuity exactly at
the location of the radio relic using existing XMM-Newton observations but we are unable
to constrain its temperature. We have been awarded XMM-Newton observation from
AO22, focusing on the radio relic, to confirm the surface brightness edge and to constrain
its temperature. The observation (0922550101) was taken in January 2024. This study will
provide unique insight into the acceleration mechanism of relativistic electrons and
provide an opportunity to search for any potential Inverse Compton emission.
