Black holes and neutron stars may collide unseen in dense star clusters

A collision between a black hole and a neutron star would unleash huge amounts of energy, but it might not generate any detectable light, a surprising new study finds.

They're overstating the importance of the cluster. A black hole doesn't need to be in a cluster to be large enough to swallow a neutron star whole and thus trigger a "lightless" collision. Yes, you're more likely to find a large black hole in a dense cluster, but you're more likely to find everything in a dense cluster. In other words, it's not a requirement. I see nothing here that indicates the cluster is necessary to trigger these sorts of collisions.
