TL;DR: The results from a new search for candidate galaxies at z ~ 8.5-11 discovered over the 850 arcmin^2 area probed by the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS) are presented in this paper.

TL;DR: In this article, the authors used the Hubble Space Telescope pure parallel imaging to select galaxy candidates at a time 500 to 650 million years after the Big Bang, which corresponds to redshifts z ~ 8-10.

TL;DR: In this article, Chandra X-ray observations of PSO J352 were used to identify a diffuse structure 50 kpc to the NW of the quasar along the jet axis and can be ruled out as a background fluctuation with a probability of P=0.9985.

TL;DR: In this article , the authors used the MOSFIRE near-infrared spectrograph on the 10 m Keck telescope to search for Lyα emission from candidate galaxies at z ∼ 9-10 in four of the CANDELS fields (GOODS-N, EGS, UDS, and COSMOS).
