Is there any possible connection between Gamma Ray Burst and Fast Radio Bursts? The physical nature of Fast Radio Bursts (FRBs), a new type of cosmological transients discovered recently, is not known. It has been suggested that FRBs can be produced when a spinning supra-massive neutron star loses centrifugal support and collapses to a black hole. 

Here we suggest that such implosions can happen in supra-massive neutron stars shortly (hundreds to thousands of seconds) after their births, and an observational signature of such implosions may have been observed in the X-ray afterglows of some long and short Gamma-Ray Bursts (GRBs). 

Under this picture, a small fraction of FRBs would be physically connected to GRBs. Is there any possible connection between Gamma Ray Bursts and Fast Radio Bursts ??
There is a tentative detection of a GRB simultaneously with an FRB,  DeLaunay et al 2016. If it is true, it would mean that at least some FRBs have the same origin as some GRBs.

Theoretically many possibilities were suggested before and after this tentative, detection. For now they all remain quite speculative, and more observations are required (and planned)
For some selection of models, it could be interesting to look into citations to this paper or its references.
