Quoting from the press release:
What are the estimations of galaxy formation at present, and how "small" are these galaxies to be expected? Are there (mass) differences between the halos formed at z ~ 30, 20,... and the ones which lead to these new galaxies? Are these galaxies expected to contain stars without any metal content, or do these galaxies form in a qualitatively different ambient than the ones formed at z ~ 30, 20,...?Previously, astronomers thought the universe's birth rate had dramatically declined and only small galaxies were forming.
References would be appreciated.
