I don’t see why the phrase “major malfunction” doesn’t perfectly describe what happened to the o-rings. Those are the exact word they used on the live TV broadcast.

I think you mean parse. But the reason the paper was only published today is because nobody noticed the supernova back then. The team went back and was looking for gravitationally lensed transient events in archival HST images, and happened to find this supernova.

Compared to supermassive black holes, yes that is obviously small, but it’s a pretty normal size for a stellar black hole. In fact the smallest stellar remnant that would become a black hole is around 2-3 solar masses, so this black hole is not the smallest possible.
