I remember that a few months ago the news of a possible a black hole-neutron star merger detected with LIGO/VIRGO was diffused.

Was this discovery confirmed?

    $\begingroup$ See en.wikipedia.org/wiki/List_of_gravitational_wave_observations. In the table in section "Observation candidates from O3/2019" the column "NS/BH" gives the probability that one component was a neutron star and the other was a black hole. For example S190814bv is assessed as a 99.8% probability of being a NS/BH merger. $\endgroup$

During O1 and O2 run there was a detection with a low probability of a NS-BH merger, but physicists are sure it was a BBH merger.

However, lets be optimititc because LIGO/Virgo have measured 5 NS-BH mergers in the O3 run. I have been told that LIGO is going to do in April a press conference talking about all these results. Lets be patient until then.

Even more, KAGRA, the japanese observatory for gravitacional waves is about to start measuring too in late February.
