On the detection of multiple shock fronts in A1914 using deep Chandra X-ray observations

ABSTRACT Here, we report the new detection of three shock fronts using archival Chandra X-ray observations in Abell 1914, which also hosts a radio halo, phoenix, and head–tail galaxy. In this study, front at position further strengthens scenario that phoenix traces old plasma gets lit up when compressed by passage. We analyse thermodynamic structure cluster detail. create temperature maps A1914 different techniques, namely adaptive circular binning, weighted Voronoi tessellations, contour binning method. These maps, along with pseudo-pressure pseudo-entropy for cluster, are evidence disturbed morphology produced multiple merger events. events cluster-wide turbulence, may reaccelerate relativistic particles result halo within cluster. Further, comparing images reveals is contained two fronts. Our analysis suggests has both equatorial axial cluster’s intracluster medium. proposed dual merging based on obtained from deeper observations.
