TL;DR: Matsuoka et al. as discussed by the authors reported discovery of 41 new high-z quasars and luminous galaxies, which were spectroscopically identified at 5.7 ≤ z ≤ 6.9.

TL;DR: In this paper, the discovery of a new ultra-faint dwarf satellite companion of the Milky Way was reported based on early survey data from the Hyper Suprime-Cam Subaru Strategic Program.
Silverrush. VII. Subaru/HSC identifications of 42 protocluster candidates AT z - 6 − 7 with the spectroscopic redshifts up to z = 6.574: Implications for cosmic reionization

TL;DR: In this article, the cosmological Lya radiative transfer (RT) model reproducing LAEs with the reionization effects was compared with the Lya rest-frame equivalent width, and it was shown that more than half of these protocluster candidates are progenitors of the present-day clusters with a mass of > 10^14 M_sun.

TL;DR: In this article, the distribution of the distance between quasars and the nearest protoclusters and the significance of the overdensity at the position of quasARS are statistically identical to those found for $g$-dropout galaxies, suggesting that quasar tend to reside in almost the same environment as star-forming galaxies at this redshift.
The environmental dependence of galaxy properties at z = 2
TL;DR: In this article, the authors investigated the environmental dependence of galaxy properties at z = 2.15 and found that the PKS1138 galaxies have similar ages, shorter star formation time scales, lower star formation rates, and weaker dust extinction compared to the GOODS galaxies at z ~ 2.
