Inferring physical properties of stellar collapse by third-generation gravitational-wave detectors

Understand

Galactic core-collapse supernovae are among the possible sources of gravitational waves.

• We investigate the ability of gravitational-wave observatories to extract the properties of the collapsing progenitor from the gravitational waves radiated.
• We use simulations of supernovae that explore a variety of progenitor core rotation rates and nuclear equations of state and examine the ability of current and future observatories to determine these properties using gravitational-wave parameter estimation.
• We use principal component analysis of the simulation catalog to determine the dominant features of the waveforms and create a map between the measured properties of the waveform and the physical properties of the progenitor.
