LIGO Document T1400219-v1
- Core-collapse supernovae (CCSN) are theorized to produce gravitational waves that can be de- tected by observatories such as Advanced LIGO. We present results from detailed 2D, axisymmetric, equatorially symmetric, general relativistic simulations of core-collapse supernovae in the bounce and post-bounce phases, investigating the effects of precollapse differential rotation and central angular velocity on post-bounce stellar dynamics and gravitational wave signals. We conclude that the dis- tribution of angular momentum is detectable primarily in CCSN from rapidly rotating progenitor stars. We employ matched filtering and Bayesian analysis with principle component decomposition to determine the potency of observed disparities among the model waveforms.
