Identification of Absorption Lines of Heavy Metals in the Wavelength Range 0.97--1.32 Micron

Noriyuki Matsunaga, Daisuke Taniguchi, Mingjie Jian +13

Stellar absorption lines of heavy elements can give us various insights into the chemical evolution of the Galaxy and nearby galaxies. Recently developed spectrographs for the near…

Possible progression of mass flow processes around young intermediate-mass stars based on high-resolution near-infrared spectroscopy. I. Taurus

Chikako Yasui, Satoshi Hamano, Kei Fukue +12

We used the WINERED spectrograph to perform near-infrared high-resolution spectroscopy (resolving power ,000) of 13 young intermediate-mass stars in the Taurus star-forming…

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). X. Discovery of 35 Quasars and Luminous Galaxies at 5.7 z 7.0

Yoshiki Matsuoka, Kazushi Iwasawa, Masafusa Onoue +44

We report the discovery of 28 quasars and 7 luminous galaxies at 5.7 z 7.0. This is the tenth in a series of papers from the Subaru High-z Exploration of Low-Luminosity…

FeI lines in 0.91-1.33 m spectra of red giants for measuring the microturbulence and metallicities

Sohei Kondo, Kei Fukue, Noriyuki Matsunaga +16

For a detailed analysis of stellar chemical abundances, high-resolution spectra in the optical have mainly been used, while the development of near-infrared (NIR) spectrograph has…

Discovery of the First Low-Luminosity Quasar at z > 7

Yoshiki Matsuoka, Masafusa Onoue, Nobunari Kashikawa +45

We report the discovery of a quasar at z = 7.07, which was selected from the deep multi-band imaging data collected by the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey.…
