Supernovae and Cosmic Expansion History Observed

• Type Ia supernovae simulations: , explosion
• SN Ia 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:
  • less technical presentation here
  • more technically: here and here; and their implications: High-z figure
  • recent data: SNLS team Hubble diagram, cosmo parameters (Sullivan et al 2011)
    Pan-STARRS Hubble diagram, Omega_Lambda vs Omega_matter (Rest et al 2013)
• Acceleration discovery is prizeworthy
