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…

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). IV. Discovery of 41 Quasars and Luminous Galaxies at 5.7 < z < 6.9

Y. Matsuoka, K. Iwasawa, M. Onoue +44

We report discovery of 41 new high-z quasars and luminous galaxies, which were spectroscopically identified at 5.7 < z < 6.9. This is the fourth in a series of papers from the Suba…
