A paper on ArXiv suggest that the two supermassive black holes in this galaxy may merge in 2022 see https://arxiv.org/pdf/2201.11633.pdf for details.
Observations of the merger could be diagnostic of what happens when 2 SM Black Holes merge. The expected signal is expected to be outside the range of the Ligo / Virgo detectors but may be visible in the EM spectrum and possibly in Neutrinos.
