Observing the Traces of Black Hole Formation
Failed explosion of massive stars is considered to be the main channel to form stellar-mass black holes seen in electromagnetic and gravitational waves. Though we likely cannot see these events as spectacular supernovae, mass ejection can still occur due to weakening of gravity when the central core emits neutrinos. In this talk I will discuss our recent predictions on the observational consequence of these events, focusing on emission when the ejected material sweeps up the surrounding matter.
