The AGORA High-resolution Galaxy Simulations Comparison Project. X: Formation and Evolution of Galaxies at the High-redshift Frontier
Hyeonyong Kim, Ji-hoon Kim, Minyong Jung +22
Recent observations from JWST have revealed unexpectedly luminous galaxies, exhibiting stellar masses and luminosities significantly higher than predicted by theoretical models at…
The AGORA High-resolution Galaxy Simulations Comparison Project. V: Satellite Galaxy Populations In A Cosmological Zoom-in Simulation of A Milky Way-mass Halo
Minyong Jung, Santi Roca-Fàbrega, Ji-hoon Kim +18
We analyze and compare the satellite halo populations at in the high-resolution cosmological zoom-in simulations of a target halo ( mass) c…
The AGORA High-resolution Galaxy Simulations Comparison Project. VI. Similarities and Differences in the Circumgalactic Medium
Clayton Strawn, Santi Roca-Fàbrega, Joel R. Primack +26
We analyze the circumgalactic medium (CGM) for eight commonly-used cosmological codes in the AGORA collaboration. The codes are calibrated to use identical initial conditions, cosm…
Updated measurements of [O III] 88 m, [C II] 158 m, and Dust Continuum Emission from a z=7.2 Galaxy
Yi W. Ren, Yoshinobu Fudamoto, Akio K. Inoue +13
We present updated measurements of the [O III] 88 m, [C II] 158 m, and dust continuum emission from a star-forming galaxy at , SXDF-NB1006-2, by utilizing Atacama La…
The 300 pc resolution imaging of a z = 8.31 galaxy: Turbulent ionized gas and potential stellar feedback 600 million years after the Big Bang
Yoichi Tamura, Tom J. L. C. Bakx, Akio K. Inoue +16
We present the results of 300 pc resolution ALMA imaging of the [OIII] 88 m line and dust continuum emission from a Lyman break galaxy MACS0416_Y1. The velocity-inte…
Star Formation and Chemical Enrichment in Protoclusters
Keita Fukushima, Kentaro Nagamine, Ikkoh Shimizu
We examine star formation and chemical enrichment in protoclusters (PCs) using cosmological zoom-in hydrodynamic simulations. We find that the total star formation rate (SFR) in al…
JWST reveals a possible galaxy merger in triply-lensed MACS0647JD
Tiger Yu-Yang Hsiao, Dan Coe, Abdurro'uf +63
MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…
Possible Systematic Rotation in the Mature Stellar Population of a Galaxy
Tsuyoshi Tokuoka, Akio K. Inoue, Takuya Hashimoto +13
We present new observations with the Atacama Large Millimeter/submillimeter Array for a gravitationally-lensed galaxy at , MACS1149-JD1. [O III] 88-m emission is detected…
Osaka Feedback Model II: Modeling Supernova Feedback Based on High-Resolution Simulations
Yuri Oku, Kengo Tomida, Kentaro Nagamine +2
Feedback from supernovae (SNe) is an essential mechanism that self-regulates the growth of galaxies, and a better model of SN feedback is still needed in galaxy formation simulatio…
The AGORA High-resolution Galaxy Simulations Comparison Project. III: Cosmological zoom-in simulation of a Milky Way-mass halo
Santi Roca-Fàbrega, Ji-hoon Kim, Loic Hausammann +20
We present a suite of high-resolution cosmological zoom-in simulations to of a halo at , obtained using seven contemporary astrophysical simul…
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 puzzling non-detection of [O III] and [C II] from a galaxy observed with ALMA
C. Binggeli, A. K. Inoue, T. Hashimoto +12
Characterizing the galaxy population in the early Universe holds the key to understanding the evolution of these objects and the role they played in cosmic reionization. However, t…
Statistical correlation between the distribution of Ly emitters and IGM HI at mapped by Subaru/Hyper Suprime-Cam
Yongming Liang, Nobunari Kashikawa, Zheng Cai +11
The correlation between neutral Hydrogen (HI) in the intergalactic medium (IGM) and galaxies now attracts great interests. We select four fields which include several coherently st…
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…
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…
