In the population synthesis simulations of Pop III stars, many BH (black hole)-BH binaries with merger time less than the age of the Universeare formed, while NS (neutron star)-BH binaries are not. The reason is that Pop III stars have no metal so that no mass loss is expected. Then, in the final supernova explosion to NS, much mass is lost so that the semimajor axis becomes too large for Pop III NS-BH binaries to merge within. However it is almost established that the kick velocity of the order ofexists for NS from the observation of the proper motion of the pulsar. Therefore, the semimajor axis of the half of NS-BH binaries can be smaller than that of the previous argument for Pop III NS-BH binaries to decrease the merging time. We perform population synthesis Monte Carlo simulations of Pop III NS-BH binaries including the kick of NS and find that the event rate of Pop III NS-BH merger rate is. This suggests that there is a good chance of detecting Pop III NS-BH mergers in O2 (Observation run 2) of Advanced LIGO and Advanced Virgo from this autumn.
