Abstract

Early galaxy revealed in Hubble data An ultra-deep search through the full Hubble Ultra Deep Field data set has uncovered a galaxy with a redshift of z ≈ 10, equivalent to an age of only 500 million years after the Big Bang. The data also provide strong constraints on the volume density of galaxies — and hence the star formation rate — at this time. The authors conclude that the star formation rate increased by a factor of ten in the time between z ≈ 10 and z ≈ 8, implying that this period in the heart of the reionization epoch was one in which galaxies were evolving very rapidly.
