LIGO/Virgo S190814bv is the first high-probability neutron star – black hole
(NSBH) merger candidate, whose gravitational waves (GWs) triggered LIGO/Virgo
detectors at 21:10:39.012957 UT, 14 August 2019. It has a probability $>99%$
of being a NSBH merger, with a low false alarm rate (FAR) of 1 per 1.559e+25
years. For a NSBH merger, electromagnetic counterparts (especially short
gamma-ray bursts (GRBs)) are generally expected. However, no electromagnetic
counterpart has been found in the extensive follow-up observing campaign. In
the present work, we propose a novel explanation to this null result, and find
9 short GRBs as the possible electromagnetic counterparts associated with the
real NSBH merger corresponding to LIGO/Virgo S190814bv.
