TL;DR: Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2m Subaru telescope on the summit of Maunakea in Hawaii as mentioned in this paper.

TL;DR: In this article, period variations of superhumps in SU UMa-type dwarf novae based on newly obtained data and past publications were systematically surveyed and the evolution of the superhump period was found to be composed of three distinct stages: early evolutionary stage with a longer superhup period, middle stage with systematically varying periods, and final stage with shorter, stable superhum period.

TL;DR: In this article, the authors report the results of a multi-band observing campaign on the famous blazar 3C 279 conducted during a phase of increased activity from 2013 December to 2014 April, including first observations of it with NuSTAR.

TL;DR: In this paper, the authors present near-infrared spectroscopic observations of star-forming galaxies at z − 1.4 with FMOS on the Subaru Telescope and find that the deviation from the mass-metallicity relation depends on the SFR (Star-formation rate) and the half light radius: Galaxies with higher SFR and larger half light radii show lower metallicities at a given stellar mass.
