A message from the LIGO and Virgo spokespersons

The LIGO Scientific Collaboration and the Virgo Collaboration are inviting the core-collapse supernova (CCSN) astrophysics community for a 1.5 days workshop March 17-18 (Friday through noon Saturday) in Pasadena, California. The workshop hopes to bring together members of the CCSN theory/simulation community with members of the LIGO-Virgo collaboration and the broader gravitational wave community in order to address how to maximize the science output for such astrophysical searches and detections.

As the second observing run of LIGO and Virgo is well under way, we find ourselves with laser Interferometers collecting and analyzing data at unprecedented sensitivities. The detection of the gravitational waves from a core collapse supernova would be a second watershed event in the newly-born field of gravitational wave astronomy. The prospect of using such a detection, along with a multi-messenger array of detections in neutrinos and photons, promises that it could be a watershed event in the fields of nuclear and neutrino physics, as well.

Progress on modeling core collapse supernovae has been rapid within the past five years, with three-dimensional multi-physics models now emerging from a number of groups internationally. In models developed to date, consensus is emerging with regard to key phenomena in supernova environments that play an important role in launching explosion. In turn, these phenomena are imprinted in important signatures associated with supernovae – in particular, their gravitational wave signatures. While work on modeling and developing algorithms for core collapse supernovae will continue into the foreseeable future, the state of the art has advanced sufficiently to begin to organize and discuss what we already know. The possibility of a detection by existing gravitational wave and neutrino observatories compel us to move forward to prepare fully for such an eventuality.

This workshop will gather together experts in both core collapse supernova astrophysics and gravitational wave astronomy. The purpose of the workshop will be to assess the current predictive state of the art as it pertains to core collapse supernova gravitational waves, to assess the shortcomings in our ability to predict details of core collapse supernova gravitational wave signatures that may impair our ability to maximize the physics output of such a detection, to identify paths forward to address these shortcomings, and to begin what is intended to be an ongoing conversation and collaboration between the two participating communities.
