V. satellite galaxy populations in a cosmological zoom-in simulation of a Milky Way-Mass HaloJung, MinyongThe AGORA CollaborationCeverino Rodríguez, DanielDark mattergalaxy halosmilky wayFísicaArtículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, el nombre del grupo de colaboración, si le hubiere, y los autores pertenecientes a la UAMWe analyze and compare the satellite halo populations at z ∼ 2 in the high-resolution cosmological zoom-in simulations of a 1012 M ⊙ target halo (z = 0 mass) carried out on eight widely used astrophysical simulation codes (Art-I, Enzo, Ramses, Changa, Gadget-3, Gear, Arepo-t, and Gizmo) for the AGORA High-resolution Galaxy Simulations Comparison Project. We use slightly different redshift epochs near z = 2 for each code (hereafter “z ∼ 2”) at which the eight simulations are in the same stage in the target halo’s merger history. After identifying the matched pairs of halos between the CosmoRun simulations and the DMO simulations, we discover that each CosmoRun halo tends to be less massive than its DMO counterpart. When we consider only the halos containing stellar particles at z ∼ 2, the number of satellite galaxies is significantly fewer than that of dark matter halos in all participating AGORA simulations and is comparable to the number of present-day satellites near the Milky Way or M31. The so-called “missing satellite problem” is fully resolved across all participating codes simply by implementing the common baryonic physics adopted in AGORA and the stellar feedback prescription commonly used in each code, with sufficient numerical resolution (≲100 proper pc at z = 2). We also compare other properties such as the stellar mass-halo mass relation and the mass-metallicity relation. Our work highlights the value of comparison studies such as AGORA, where outstanding problems in galaxy formation theory are studied simultaneously on multiple numerical platformsWe thank all of our colleagues participating in the AGORA Project for their collaborative spirit, which has enabled the Collaboration to remain strong as a platform to foster and launch multiple science-oriented comparison efforts. We particularly thank Oscar Agertz, Kirk Barrow, Oliver Hahn, Desika Narayanan, Eun-jin Shin, Britton Smith, Ben Tufeld, and Matthew Turk for their insightful comments during the work presented in this paper and Yongseok Jo and Seungjae Lee for their helpful feedback on the earlier version of this manuscript. We are also grateful to Volker Springel for making the Gadget-2 code public and for providing the original versions of Gadget-3 to be used in the AGORA Project.
