Extreme nature of four blue-excess dust-obscured galaxies revealed by optical spectroscopy

Akatoki Noboriguchi, Tohru Nagao, Yoshiki Toba +13

We report optical spectroscopic observations of four blue-excess dust-obscured galaxies (BluDOGs) identified by Subaru Hyper Suprime-Cam. BluDOGs are a sub-class of dust-obscured g…

Optical IFU Observations of GOALS Sample with KOOLS-IFU on Seimei Telescope: Initial results of 9 U/LIRGs at 0.04

Yoshiki Toba, Satoshi Yamada, Kazuya Matsubayashi +23

We present ionized gas properties of 9 local ultra/luminous infrared galaxies (U/LIRGs) at 0.04 through IFU observations with KOOLS-IFU on Seimei Telescope. The observed targ…

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XVI. 69 New Quasars at 5.8 < z < 7.0

Yoshiki Matsuoka, Kazushi Iwasawa, Masafusa Onoue +41

We present the spectroscopic discovery of 69 quasars at 5.8 < z < 7.0, drawn from the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) imaging survey data. This is the 16th p…

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). IX. Identification of Two Red Quasars at z > 5.6

Nanako Kato, Yoshiki Matsuoka, Masafusa Onoue +14

We present the first discovery of dust-reddened quasars (red quasars) in the high-z universe (z >5.6). This is a result from the Subaru High-z Exploration of Low-Luminosity Quasars…

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…

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). VI. Black Hole Mass Measurements of Six Quasars at 6.1<z<6.7

Masafusa Onoue, Nobunari Kashikawa, Yoshiki Matsuoka +14

We present deep near-infrared spectroscopy of six quasars at 6.1<z<6.7 with VLT/X-Shooter and Gemini-N/GNIRS. Our objects, originally discovered through a wide-field optical survey…
