The Faint End of the Quasar Luminosity Function at from the Subaru Hyper Suprime-Cam Survey

Mana Niida, Tohru Nagao, Hiroyuki Ikeda +17

We present the quasar luminosity function at derived from the optical wide-field survey data obtained as a part of the Subaru strategic program (SSP) with Hyper Suprime-…

Revisiting Soltan's argument based on a semi-analytical model for galaxy and black hole evolution

Hikari Shirakata, Toshihiro Kawaguchi, Takashi Okamoto +2

We show the significance of the super-Eddington accretion for the cosmic growth of supermassive black holes (SMBHs) with a semi-analytical model for galaxy and black hole evolution…

Quantifying the effect of field variance on the H luminosity function with the New Numerical Galaxy Catalogue (GC)

Kazuyuki Ogura, Masahiro Nagashima, Rhythm Shimakawa +9

We construct a model of H emitters (HAEs) based on a semi-analytic galaxy formation model, the New Numerical Galaxy Catalog (GC). In this paper, we report our estimate for…

Semi-analytic modelling of AGNs: auto-correlation function and halo occupation

Taira Oogi, Hikari Shirakata, Masahiro Nagashima +5

The spatial clustering of active galactic nuclei (AGNs) is considered to be one of the important diagnostics for the understanding of the underlying processes behind their activiti…

Slowing down of cosmic growth of supermassive black holes: Theoretical prediction of the Eddington ratio distribution

Hikari Shirakata, Toshihiro Kawaguchi, Taira Oogi +2

We show the Eddington ratio distributions of supermassive black holes at a wide redshift range (0 < z < 8) obtained with a semi-analytic model of galaxy formation. The distribution…

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) VIII. A less biased view of the early co-evolution of black holes and host galaxies

Takuma Izumi, Masafusa Onoue, Yoshiki Matsuoka +24

We present ALMA [CII] line and far-infrared (FIR) continuum observations of three low-luminosity quasars () discovered by our Subaru Hyper Suprime-Cam (…
