So I guess these “failed supernovae” would be core collapse supernovae. I’ve read that pair-instability supernovae can also create superluminous supernovae, but these seem to do the opposite i.e. blow the star apart so violently that it leaves no remnant.

Is the idea then that the SLSNe we do see are pair-instability supernovae while these core collapse-style, failed supernovae prevent the remaining, otherwise potential SLSNe, to be snuffed out?
