Although the aLIGO/Virgo collaboration has reported detections of a few neutron star-black holes (NSBH) binaries merger candidates, so far there are no electromagnetic counterparts associated with these events as those linked to GW170817. As a step forward in solidifying NSBHs as multimessenger sources, I have demonstrated, for the first time in full general relativity, that if the initial spin of the BH is larger than 0.5 and the mass ratio MNS/MBH = 3 then NSBH systems can launch a magnetically-driven jet. The lifetime of the jets and their outgoing Poynting luminosities [Ljet ~ 1052 erg/s] are consistent with typical sGRBs, as well as with the Blandford–Znajek mechanism for launching jets and their associated Poynting luminosities.
