Comparison of cosmological simulations and deep submillimetre galaxy surveys
Shohei Aoyama, Hiroyuki Hirashita, Chen-Fatt Lim +8
Recent progress in submillimetre surveys by single-dish telescopes allows us to further challenge the consistency between cosmological simulations and observations. In particular,…
Redshift Space Distortion of 21cm line at 1<z<5 with Cosmological Hydrodynamic Simulations
Rika Ando, Atsushi J. Nishizawa, Kenji Hasegawa +2
We measure the scale dependence and redshift dependence of 21 cm line emitted from the neutral hydrogen gas at redshift 1<z<5 using full cosmological hydrodynamic simulations by ta…
Detection of the Far-infrared [O III] and Dust Emission in a Galaxy at Redshift 8.312: Early Metal Enrichment in the Heart of the Reionization Era
Yoichi Tamura, Ken Mawatari, Takuya Hashimoto +19
We present the Atacama Large Millimeter/submillimeter Array (ALMA) detection of the [O III] 88 m line and rest-frame 90 m dust continuum emission in a Y-dropout Lyman break g…
"Big Three Dragons": a z = 7.15 Lyman BreakGalaxy Detected in [OIII] 88 m, [CII] 158 m, and Dust Continuum with ALMA
Takuya Hashimoto, Akio K. Inoue, Ken Mawatari +18
We present new ALMA observations and physical properties of a Lyman Break Galaxy at z=7.15. Our target, B14-65666, has a bright ultra-violet (UV) absolute magnitude, $M_{\rm UV}\ap…
The onset of star formation 250 million years after the Big Bang
Takuya Hashimoto, Nicolas Laporte, Ken Mawatari +21
A fundamental quest of modern astronomy is to locate the earliest galaxies and study how they influenced the intergalactic medium a few hundred million years after the Big Bang. Th…
The distribution and physical properties of high-redshift [OIII] emitters in a cosmological hydrodynamics simulation
Kana Moriwaki, Naoki Yoshida, Ikkoh Shimizu +7
Recent observations with the Atacama Large Millimeter/submillimeter Array (ALMA) detected far-infrared emission lines such as the [OIII] 88 μm line from galaxies at .…
Lyman continuum leakage versus quenching with the James Webb Space Telescope: The spectral signatures of quenched star formation activity in reionization-epoch galaxies
C. Binggeli, E. Zackrisson, K. Pelckmans +3
In this paper, we study the effects of a recent drop in star formation rate (SFR) on the spectra of epoch of reionization (EoR) galaxies, and the resulting degeneracy with the spec…
Cosmological simulation with dust formation and destruction
Shohei Aoyama, Kuan-Chou Hou, Hiroyuki Hirashita +2
To investigate the evolution of dust in a cosmological volume, we perform hydrodynamic simulations, in which the enrichment of metals and dust is treated self-consistently with sta…
SILVERRUSH. VI. A simulation of Ly emitters in the reionization epoch and a comparison with Subaru Hyper Suprime-Cam survey early data
Akio K. Inoue, Kenji Hasegawa, Tomoaki Ishiyama +12
The survey of Lyman emitters (LAEs) with Subaru Hyper Suprime-Cam, called SILVERRUSH (Ouchi et al.), is producing massive data of LAEs at . Here we present LAE simul…
