- Аннотация: We discuss the recently reported discovery of fast radio bursts (FRBs) in the frame- work of the neutron star-neutron star (NS+NS) or neutron star-black hole (NS+BH) binary merger model. We concentrate on what we consider to be an issue of greatest im- portance: what is the NS merger rate given that the FRB rate (1/1000 yr (-1) per galaxy) is inconsistent with gamma-ray burst rate as discussed by Thornton and should be significantly higher. We show that there is no discrepancy between NS merger rate and observed FRB rates in the framework of the Scenario Machine population syn- thesis - for a kick velocity of 100-150 km s (-1) an average NS merger rate is 1/500- 1/2000 yr (-1) per galaxy up to z = 0.5-1. Based on the Scenario Machine NS merger rate estimates, we discuss the lack of positive detections on the ground-based interferom- eters, considering the LIGO (Laser Interferometer Gravitational-wave Observatory).
