Nonradial neutrino emission upon black hole formation in core collapse supernovae

Core-collapse supernovae resulting in black hole formation are expected to feature a precipitous decline neutrino luminosity. The authors provide considerable nuance this picture by considering non-radial emission both the spherically symmetric (Schwarzschild) and rotating (Kerr) cases. In each of these cases, they show that neutrinos affect luminosity cut-off shape interesting ways indicate rich domain for further theoretical observational exploration.
