Summary

• Measurements:

  • 0.16 - 3.5 micron: still quite uncertain
  • 3.5 - 140 micron: similarly uncertain (IPD)
  • 140 - 1000 microns: most certain

• Star light (52%) and dust (48%) but uncertainties of factor of 4!

• 30% more dust than in local universe

• EBL does not imply a unique star formation history

• Models generally consistent with EBL intensity and shape
