Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). V. Quasar Luminosity Function and Contribution to Cosmic Reionization at z = 6
Yoshiki Matsuoka, Michael A. Strauss, Nobunari Kashikawa +44
We present new measurements of the quasar luminosity function (LF) at , over an unprecedentedly wide range of the rest-frame ultraviolet luminosity from …
The mass-metallicity relation of high-z type-2 active galactic nuclei
Kenta Matsuoka, Tohru Nagao, Alessandro Marconi +5
The mass-metallicity relation (MZR) of type-2 active galactic nuclei (AGNs) at 1.2 < z < 4.0 is investigated by using high-z radio galaxies (HzRGs) and X-ray selected radio-quiet A…
A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). I. The Optical Counterparts of FIRST Radio Sources
Takuji Yamashita, Tohru Nagao, Masayuki Akiyama +12
We report the result of optical identifications of FIRST radio sources with the Hyper Suprime-Cam Subaru Strategic Program survey (HSC-SSP). The positional cross-match within 1" be…
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…
