Here we provide theoretical gravitational-wave signal predictions from a variety of core-collapse simulations carried out in recent years. This is a service to the community and in an effort to further and nurture collaboration between supernova theorists and the gravitational wave data analysis community. All waveforms are freely available for download and we kindly request that in the case of a publication involving these GW signal data stellarcollapse.org be acknowledged and the original paper in which the waveforms were first published be cited.

If you have GW signal predictions you would like to make available on or link to from stellarcollapse.org, please e-mail us at   .

For a review of gravitational wave emission in core-core collapse supernovae, see the Classial & Quantum Gravity Topical Review, C. D. Ott, CQG 26, 063001 (2009) (ads):

GW signal data from the following studies are available on stellarcollapse.org. Please feel free to contact Christian D. Ott (cott at tapir.caltech.edu) with any questions or comments you might have.
