The search for X-ray emission from Fast Radio Burst: current status and future prospects.

Abstract: Fast radio bursts (FRBs) are bright, millisecond-duration radio bursts originating from outside our Milky Way galaxy. Their physical origin remains a an open question in astrophysics. No confirmed multiwavelength counterpart has yet been detected for an extragalactic FRB. The X-ray burst that accompanied the FRB-like radio burst from the Galactic magnetar SGR 1935+2154 provides evidence for a magnetar origin for some fraction of the FRB population and strongly motivates the search for X-ray bursts from nearby FRB sources. Connections to other X-ray sources, e.g. ULXs have also been suggested for FRBs. X-ray observations thus represent a valuable probe of FRB progenitors and emission mechanisms. In this talk I will review existing and future FRB searches, overview existing limits on X-ray emission from FRB sources using current instrumentation, and forecast what will be possible using future instruments, including NewAthena.
