Subaru High- Exploration of Low-Luminosity Quasars (SHELLQs). XXV. Large-scale environments of low-luminosity quasars at traced by Ly emitters
Junya Arita, Nobunari Kashikawa, Yoshiki Matsuoka +18
High- quasars are believed to reside in massive dark matter haloes (DMHs), suggesting that they reside in galaxy overdense regions. However, previous observations have shown a r…

Reconstruction of Cosmic Black Hole Growth and Mass Distribution from Quasar Luminosity Functions at : Implications for Faint and Low-mass Populations in JWST
Wenxiu Li, Kohei Inayoshi, Masafusa Onoue +6
The evolution of the quasar luminosity function (QLF) is fundamental to understanding the cosmic evolution of black holes (BHs) through their accretion phases. In the era of the Ja…
