SIMULTANEOUS XMM-NEWTON AND RADIO OBSERVATIONS OF REPEATING FAST RADIO BURSTS

We propose to observe nearby repeating fast radio bursts (FRBs) with XMM Newtonto probe for Xray counterparts to radio bursts. This will test whether they areconsistent with predictions from young magnetar progenitor theories. Recentevidence, such as the detection of a FRBlike burst from the Galactic magnetarSGR 1935+2154, suggests that magnetars may be the engines of at least some FRBs.We will compare Xray observables, like burst luminosity and temporalproperties, to those predicted from magnetar progenitor theories. To probe asdeep as possible, we will provide fully simultaneous radio coverage to providetimes of radio bursts during the XMM observations. This will allow us to searchfor Xray bursts in as narrow a time and spatial window as possible. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
