First Galaxies

(targeted highest red-shift galaxies showing little or no metal)

First Galaxies are targets of some searches, e.g., Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), typically searching in Near Infrared (NIR). The goal is to find galaxies with ever higher Redshifts (z), with little or no Metal. Candidates are in the Z=7 to 12 range.
