Abstract:

Glitches in pulsar timing are thought to be associated with sudden changes in the pulsar's angular momentum. A fraction of the excess rotational energy is then radiated away as gravitational wave emission. We present a search for damped-sinusoidal gravitational wave ringdowns using Bayesian model selection. We demonstrate how the result from such a search is easily converted into a statement about the physical properties of the gravitational wave emission.
