סמינר באסטרונומיה ובאסטרופיזיקה: Gravitational radiation from cosmic explosions

Abstract:

I shall describe plausible mechanisms for gravitational wave emission from hyper-accreting black holes in core collapse supernovae. Three main channels are identified: broadband emission from non-axisymmetric wave patterns in the accretion flow, fragmentation chirps, and ISCO chirps in cases where feedback from the black hole via magnetic coupling is established. Given the rate of type Ib/c SNe (or just the subclass associated with LGRBs and LLGRBs), these objects should be considered as potential targets for advanced gravitational wave detectors.
