Subaru High-$z$ Exploration of Low-Luminosity Quasars (SHELLQs). XXIII. The powering mechanisms of the Ly$\alpha$ haloes around high-$z$ quasars probed by slit spectroscopy

Hiroki Hoshi, Rikako Ishimoto, Nobunari Kashikawa +15

We present the analysis of Ly$\alpha$ haloes around faint quasars at $z\sim 4$ and $z\sim 6$. We use 20 and 162 quasars at $z\sim 4$ and $z\sim 6$, taken by slit spectroscopy, and detect Ly…
