The physical origin for spatially large scatter of IGM opacity at the end of reionization: the IGM Ly$\alpha$ opacity-galaxy density relation

Rikako Ishimoto, Nobunari Kashikawa, Daichi Kashino +9

The large opacity fluctuations in the $z>5.5$ Ly$\alpha$ forest may indicate inhomogeneous progress of reionization. To explain the observed large scatter of the effective Ly$\alpha$ optic…
