Identification of AKARI infrared sources by Deep HSC Optical Survey: Construction of New Band-Merged Catalogue in the NEP-Wide field
Seong Jin Kim, Nagisa Oi, Tomotsugu Goto +21
The north ecliptic pole (NEP) field is a natural deep field location for many satellite observations. It has been targeted manytimes since it was surveyed by the AKARI space telesc…
CHORUS. I. Cosmic HydrOgen Reionization Unveiled with Subaru: Overview
Akio K. Inoue, Satoshi Yamanaka, Masami Ouchi +28
To determine the dominant sources for cosmic reionization, the evolution history of the global ionizing fraction, and the topology of the ionized regions, we have conducted a deep…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XI. Proximity Zone Analysis for Faint Quasar Spectra at z~6
Rikako Ishimoto, Nobunari Kashikawa, Masafusa Onoue +14
We present measurements of the size of the quasar proximity zone () for eleven low-luminosity () quasars at , discovered by the Subaru H…
Probing Feedback via IGM tomography and Ly forest with Subaru PFS, TMT/ELT, and JWST
Kentaro Nagamine, Ikkoh Shimizu, Katsumi Fujita +8
In preparation for the IGM tomography study by Subaru Prime Focus Spectrograph (PFS) survey and other large future telescopes such as TMT/ELT/GMT, we present the results of our pil…
Search for Optically Dark Infrared Galaxies without Counterparts of Subaru Hyper Suprime-Cam in the AKARI North Ecliptic Pole Wide Survey Field
Yoshiki Toba, Tomotsugu Goto, Nagisa Oi +25
We present the physical properties of AKARI sources without optical counterparts in optical images from the Hyper Suprime-Cam (HSC) on the Subaru telescope. Using the AKARI infrare…
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…
Connection Between Galaxies and HI in the Circumgalactic and Intergalactic Media: Variation According to Galaxy Stellar Mass and Star-formation Activity
Rieko Momose, Ikkoh Shimizu, Kentaro Nagamine +3
This paper systematically investigates comoving Mpc scale intergalactic medium (IGM) environment around galaxies traced by the Ly forest. Using our cosmological hydrodynamic sim…
