Supernovae and Cosmic Acceleration

• Type Ia supernovae as standard candles
  • Search Teams: Supernova Cosmology Project, High-z Supernova Search
  • Examples: low-z SN 1994D, typical medium-z event, z=1.7 discovery in the Hubble Deep Field
  • light curves
• probing cosmic expansion history using supernovae as standard candles
• Bizarre results here and here; and their implications: High-z figure
• Coincidences: cosmic epochs in perspective
• Dark energy and future efforts to measure it: Dark Energy Survey, SNAP
