Progress on Dark Energy using SNIa
• Essential for – w0, w’ constraints– Progess in systematics:
• Host galaxies• Colors (rest frame UV)• SNxx contamination• Spectra• Evolution
– Progenitors and IC’s
• Want >10,000, need 1000• Wide field, optical colors
• Essential for– w0, w’ constraints
– Immunity to systematics
• Want 300, need 30• Use z, J, H, and grism• Challenge is improving

Three Futures• No servicing; HST dies in 2008
– Our ~30 SNIa at z>1 remain a legacy for next 10 years of ground based observation (restricted to z<1)
(DE, w0, w’) = (0.1, 0.3, 0.8)
• HST sleeps in 2007; RM1 in 2009; WFC3 installed– Search CDF and HDF with WF3 / IR. Find SNIa at 1.3 < z < 2.0
at a rate of one per 10 – 20 orbits? ACS parallels? JWST??? (DE, w0, w’) = (0.05, 0.2, 0.4)
• RM2 in 2012 to prove robotics technology for NASA– HUFI-red finds SNIa at 1.0 < z < 1.8 at a rate of 1 – 2 per orbit, IR
light curves from WF3 and JWST, redshifts from JWST (DE, w0, w’) = (0.05, 0.1, 0.2)

Supernova Systematics• Uninteresting (avoidable)
– Photometry error (0.03 0.01)– UV SEDs (0.05 0.00)– Poor LC coverage (0.04 0.00)– Host extinction (0.06 0.03)
• Interesting (intrinsic)– SN1a: progenitor, initial conditions, trigger (z)– Host extinction and properties (z)– Gravitational lensing (z)– Transparency of IGM (z)

Hubble Symposium 5 May 04
What Causes the Diversity?
• Progenitors may have different– Mass (luminosity ~ 56Ni mass)– Metallicity (Z n 56Ni )– Age (22Ne sedimentation?)– Binary companion (???)– Mass transfer mechanism (???)
• Explosion may have different– Trigger mechanism (???)– Propagation (deflagration/detonation, “weather”, etc)
• Good news: – Chandresekhar mass and NSE make explosions quite uniform
(~50% and 1 parameter gets us to ~20%)
• Bad news:– Plenty of room for unknown systematics at the 2% level
