The Peak Epoch of Star Formation (Peak Star-Formation Epoch, Epoch of Peak Star Formation, or just Peak Epoch, or Cosmic High Noon) on the order of 10 billion years ago (Lookback Time) at a Redshift on the order of 2, is the time when Star Formation across the universe was at its peak.
The Peak Epoch is determined by surveying the Star Formation Rate across the sky, across redshifts, using normal Star Formation Rate estimation methods adjusted for redshift.
