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 (…
Discovery of the First Low-Luminosity Quasar at z > 7
Yoshiki Matsuoka, Masafusa Onoue, Nobunari Kashikawa +45
We report the discovery of a quasar at z = 7.07, which was selected from the deep multi-band imaging data collected by the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey.…
