Fast
Radio Bursts (FRBs) are fast, millisecond-duration, extremely bright
(~Jy) bursts that have so far only been observed at radio wavelengths.
Only a small fraction of them, the so called repeaters, have been
observed more than once and their multiple detections have shaped the
theories on their -still nebulous- origin towards a possible young
magnetar progenitor.
The recent localisation of the very active,
nearby (150 Mpc) repeater, FRB 180916, for which, for the first time,
periodicity was also identified (a 5 day active cycle every 16.3 days)
sparked new life into the search of multiwavelength counterparts.In
addition to this, the last year has witnessed the first possible
smoking gun of a magnetar-FRB connection with the detection of X-ray
emission accompanying the radio burst.
I will present an overview of the efforts towards the detection of the -so far elusive- multiwavelength counterpart of an FRB, with particular emphasis on the work led by Italian teams in radio, optical, X-rays and gamma-rays. I will discuss the challenges to this task in light of models’ predictions and will outline the future prospects for multiwavelength campaigns targeting repeater FRBs.
