Title: Revealing the Sources of High-Energy Astrophysical Neutrinos
Abstract: The IceCube neutrino observatory opened a new chapter of multi-messenger astronomy in 2013 with the discovery of astrophysical neutrinos at TeV to PeV energies, whose origin is still unknown. Due to their low interaction cross section, neutrinos permit a deep view into otherwise opaque sources, and allow exploration at higher energies than can be probed by electromagnetic radiation. To facilitate the identification of electromagnetic counterparts via time-domain searches, IceCube has begun issuing realtime public alerts for the highest confidence and best-localized neutrino events (median angular uncertainty < 1.0 deg. We propose ToO follow-up observations with Blanco/DECam (gri to 24th magnitude in ~6 epochs) during time allocated to the Dark Energy Survey (DES) to search for explosive optical transients, such as core collapse supernovae, coincident with 4 neutrino alerts. Plausibly associated sources would then be spectroscopically characterized with Gemini/GMOS-S. By targeting several neutrino events per semester, beginning in 2017B, we can reasonably expect to identify the first individual TeV-PeV neutrino source, or else place meaningful constraints on internal physical processes occurring within core-collapse supernovae and other explosive optical transients.
