P5 Report to HEPAP
* Cosmic Frontier Recommendations– Support for the study of dark matter and dark
energy as an integral part of the US particle physics program.
– DOE support the space-based Joint Dark Energy Mission, in collaboration with NASA, at an appropriate level negotiated with NASA.
– DOE support for the ground-based Large Synoptic Survey Telescope program in coordination with NSF at a level that depends on the overall program budget.
– Joint NSF and DOE support for direct dark matter search experiments.
– Limited R&D funding for other particle astrophysics projects and recommends establishing a Particle Astrophysics Science Advisory Group.
