FOREVER22: galaxy formation in protocluster regions
Hidenobu Yajima, Makito Abe, Sadegh Khochfar +14
We present results from a new cosmological hydrodynamics simulation campaign of protocluster (PC) regions, FOREVER22: FORmation and EVolution of galaxies in Extremely-overdense Reg…
Starbursting [O III] emitters and quiescent [C II] emitters in the reionization era
Shohei Arata, Hidenobu Yajima, Kentaro Nagamine +2
Recent observations have successfully detected [O III] and [C II] lines from galaxies in the early Universe with the Atacama Large Millimeter Arr…
Galaxy evolution and radiative properties in the early Universe: multi-wavelength analysis in cosmological simulations
Shohei Arata, Hidenobu Yajima, Kentaro Nagamine +2
Recent observations have successfully detected UV or infrared flux from galaxies at the epoch of reionization. However, the origin of their radiative properties has not been fully…
CHORUS. III. Photometric and Spectroscopic Properties of Ly Blobs at
Haibin Zhang, Masami Ouchi, Ryohei Itoh +20
We report the Subaru Hyper Suprime-Cam (HSC) discovery of two Ly blobs (LABs), dubbed z70-1 and z49-1 at and respectively, that are Ly emitters with a bri…
First Identification of 10-kpc Scale [CII] 158um Halos around Star-Forming Galaxies at z=5-7
Seiji Fujimoto, Masami Ouchi, Andrea Ferrara +7
We report the discovery of 10-kpc scale [CII] 158um halos surrounding star-forming galaxies in the early Universe. We choose deep ALMA data of 18 galaxies each with a star-formatio…
Radiative properties of the first galaxies: rapid transition between blue and red
Shohei Arata, Hidenobu Yajima, Kentaro Nagamine +2
Recent observations have successfully detected UV-bright and infrared-bright galaxies in the epoch of reionization. However, the origin of their radiative properties has not been u…
Gas clump formation via thermal instability in high-redshift dwarf galaxy mergers
Shohei Arata, Hidenobu Yajima, Kentaro Nagamine
Star formation in high-redshift dwarf galaxies is a key to understand early galaxy evolution in the early Universe. Using the three-dimensional hydrodynamics code GIZMO, we study t…
