Catch Me if You Can: Biased Distribution of Ly-emitting Galaxies according to the Viewing Direction
Rieko Momose, Kazuhiro Shimasaku, Kentaro Nagamine +4
We report that Ly-emitting galaxies (LAEs) may not faithfully trace the cosmic web of neutral hydrogen (HI), but their distribution is likely biased depending on the viewing dir…

A Systematic Search for Galaxy Proto-Cluster Cores at
Makoto Ando, Kazuhiro Shimasaku, Rieko Momose
A proto-cluster core is the most massive dark matter halo (DMH) in a given proto-cluster. To reveal the galaxy formation in core regions, we search for proto-cluster cores at $z\si…

Environmental Dependence of Galactic Properties Traced by Ly Forest Absorption: Diversity among Galaxy Populations
Rieko Momose, Kazuhiro Shimasaku, Nobunari Kashikawa +8
In order to shed light on how galactic properties depend on the intergalactic medium (IGM) environment traced by the Ly forest, we observationally investigate the IGM-galaxy con…
