It is easiest to detect a gravitational wave signal if it has been described analytically, like those from periodic sources or binary inspirals, or statistically, like those from the big bang, or computationally. However, gravitational waves from some sources, like supernovae and the merger of two black holes, have been described in none of the above ways. Theses are called unmodelled burst sources, and at least a couple of methods for detecting them have been implemented. These methods rely heavily on understanding the noise environment in which a search is conducted, and are therefore best suited to networks of detectors where one can use coincidence criteria to limit the spurious detections due to bursts of noise.
We are currently working with Patrick Brady and the LIGO/LSC MPI working group to develop a multi-processor version of the search excess power search code written by the Cornell LSC group. We also expect to work on the signal curve tracking algorithm developed at the University of Cardiff and the Albert Einstein Institute in Germany.
