A possible connection between Fast Radio Bursts and Gamma-Ray Bursts

Understand

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).
• Within this picture, a small fraction of FRBs would be physically connected to GRBs.
