What disrupts the jets in wide-angle tail radio galaxies - testing merger models

Wideangle tail radio galaxies (WATs) are a challenge to ourunderstanding of the way in which extragalactic radio sources interactwith their environment. Neither the disruption of their jets nor the100kpcscale bending of their tails is fully understood. WATs alwaysinhabit Xrayluminous clusters, and recent cluster merger events maygive rise to observed clumpy Xray emission and to largescale winds thatbend and disrupt the jets. We propose to test this model in a smallsample of wellstudied WATs. XMM.s high sensitivity and spatialresolution will allow us to determine the nature of the clumpy gas and truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
