Description

The nature of fast radio bursts (FRBs), bright flashes of millisecond-duration and likely extragalactic origin, remains unknown. The lack of precise localizations compromises the search for multiwavelength counterparts, and their physical origin is subject to considerable debate. The detection of repeating bursts from FRB 121102 rules out a cataclysmic event as the progenitor for this object. Sub-arcsecond localization of recent bursts revealed that the source is co-located with a compact, persistent radio source in a dwarf galaxy at z=0.19. This may be consistent with a young pulsar or magnetar progenitor, for which some models predict VHE emission. The MAGIC telescopes are sensitive to both VHE gamma rays and millisecond-long optical pulses. Results of a multiwavelength campaign on the repeating FRB 121102 together with radio observations by Arecibo, Effelsberg and the EVN will be reported.
