Journal ArticleDOI
A Monster in the early Universe
TL;DR: The most distant quasar yet discovered sets constraints on the formation mechanism of black holes, and further observations of this and other distant quasars should reveal the ionization state of the Universe as it was only about 0.75 billion years after the Big Bang.
Journal ArticleDOI
Cosmology: A monster in the early Universe
TL;DR: The most distant quasar yet discovered sets constraints on the formation mechanism of black holes as discussed by the authors, and its light spectrum has tantalizing features that are expected to be observed before the reionization epoch ended.

TL;DR: In this paper , the authors constrain the rest-frame [O III]λ5007 equivalent width distribution for a sample of 76 1 < z < 3.4 SFGs in the A2744 Hubble Frontier Field and determine an abundance fraction of extreme emission line galaxies with EW > 750Å in their sample to be 12%.
