Title: Light Curves of Candidate Failed Supernova Shock Breakouts

Abstract: Evidence is growing that core collapse in the most massive red supergiants might fail to explode the star and instead result in prompt black hole formation. In such a case, it is predicted that the loss of gravitational binding energy will result in a weak shock that unbinds the hydrogen envelope. With the high-cadence survey of the Zwicky Transient Facility we will have the survey speed to potentially discover the shock breakout associated with such a ``failed" supernova. We propose LCO photometric follow-up of candidate events. This program has the potential to yield the first light curve of a failed supernova shock breakout and, when paired with other observations of the fainter, longer- lived recombination-powered transient expected to follow such an event, would provide strong evidence that we have indeed witnessed the birth of a black hole birth from stellar core-collapse.
