Coordinated X-ray and Radio Observations of the Repeating Fast Radio Burst
Abstract
FRB 121102, discovered with the Arecibo radio telescope, is the onlyknown repeating fast radio burst source. Its extragalactic nature was unambiguously established via sub-arcsecond localization using the VLA along with Gemini and Hubble optical observations, which identified the host as a faint, low-metallicity, star-forming dwarf galaxy at redshift z=0.193. Recent radio polarimetry revealed that the FRB source resides in an extreme magneto-ionic environment. In an attempt to constrain the nature of the underlying source, we have undertaken X-ray observing campaigns with Chandra, XMM-Newton, and NuSTAR in coordination with radio observations of FRB 121102 to search for X-ray burst as well as persistent counterparts. I will present the results of these observations and discuss them in the context of the host environment of this FRB and of possible sources of fast radio bursts in general. I will conclude with a review of future prospects for high energy studies of FRBs using existing and future facilities.
