  1. Dark Energy Task Force http://www.nsf.gov/mps/ast/detf.jsp • Three agencies: DOE; NASA; NSF • Two subcommittees: AAAC (Illingworth); HEPAP (Gilman) • Two charge letters: Kinney (NASA); Staffin (DOE); Turner (NSF) • Twelve members: Overlap with AAAC, HEPAP, SDT • One chair: Rocky Kolb (Fermilab/Chicago) • First meeting: March 22-23, 2005 @ NSF • Future meetings: July 1 @ FNAL; October @ UC Davis • Expectations: Final report 31 December 2005

  3. Dark Energy Task Force Charge* “The DETF is asked to advise the agencies on the optimum near- and intermediate- term programs to investigate dark energy and, in cooperation with agency efforts, to advance the justification, specification and optimization of LST and JDEM.” • Summarize existing program of funded projects • Summarize proposed and emergent approaches • Identify important steps, precursors, R&D, … • Identify areas of dark energy parameter space existing or • proposed projects fail to address • 5. Prioritize approaches (not projects) * Fair range of interpretations of charge

  4. Dark Energy Landscape* DETF SDT pre-1988 LSS theory CMB SNe H0 1998 Hi-z SCP 1998-now confirmation! ongoing many projects focus now on w, w near-term many proposed projects shape battlefield for LST/JDEM nirvana LST JDEM * Just my opinion.

  5. First Step: Call for White Papers http://www.nsf.gov/mps/ast/detf.jsp • Purpose: Education of Task Force in order to give informed recommendations • What we are looking for: • How projects can be put together in a program • Common needs • Technology • Astronomy information
