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 …
Compton Shoulder Diagnostics in Active Galactic Nuclei for Probing the Metalicity of the Obscuring Compton-Thick Tori
Masaya Hikitani, Masanori Ohno, Yasushi Fukazawa +2
We analyzed the spectral shape of the Compton shoulder around the neutral Fe-K line of the Compton-thick type II Seyfert nucleus of the Circinus galaxy. The characteristics of…
A 100-pc Scale, Fast and Dense Outflow in Narrow-Line Seyfert 1 Galaxy IRAS04576+0912
Toshihiro Kawaguchi, Shinobu Ozaki, Hajime Sugai +8
We report the initial result of an adaptive-optics assisted, optical integral-field-unit observation on IRAS04576+0912, the nearest (z=0.039) active galactic nucleus with a promine…
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…
Imaging Extended Emission-Line Regions of Obscured AGN with the Subaru Hyper Suprime-Cam Survey
Ai-Lei Sun, Jenny E. Greene, Nadia L. Zakamska +9
Narrow-line regions excited by active galactic nuclei (AGN) are important for studying AGN photoionization and feedback. Their strong [O III] lines can be detected with broadband i…
Optical properties of infrared-bright dust-obscured galaxies viewed with Subaru Hyper Suprime-Cam
Akatoki Noboriguchi, Tohru Nagao, Yoshiki Toba +11
We report on the optical properties of infrared (IR)-bright dust-obscured galaxies (DOGs) that are defined as (i-[22])_AB > 7.0. Because supermassive black holes (SMBHs) in IR-brig…
