“…Note that the median data points deviating from the fitting line at the lower halo mass is mainly caused by the weighted fitting method. Furthermore, the slightly different fitting results between this work and Cui et al (2018b) is because the new mass completeness based on G -S is adopted (see Cui (2022) for the changes). This indicates the fitting results are very sensitive to the weights.…”

We introduce G -S , a new suite of galaxy cluster simulations within T T H project. T T H consists of zoom re-simulations of 324 clusters with 𝑀 200 10 14.8 𝑀 drawn from the MultiDark-Planck 𝑁-body simulation, run using several hydrodynamic and semi-analytic codes. The G -S suite adds a state-of-the-art galaxy formation model based on the highly successful S simulation, mildly re-calibrated to match 𝑧 = 0 cluster stellar properties. Comparing to T T H zooms run with G -X, we find intrinsic differences in the evolution of the stellar and gas mass fractions, BCG ages, and galaxy colour-magnitude diagrams, with G -S generally providing a good match to available data at 𝑧 ≈ 0. G -S 's unique black hole growth and feedback model yields agreement with the observed BH scaling relations at intermediate mass range, and predicts a slightly different slope at high masses where few observations currently lie. G -S provides a new and novel platform to elucidate the co-evolution of galaxies, gas, and black holes within the densest cosmic environments.

We introduce Gizmo-Simba, a new suite of galaxy cluster simulations within The Three Hundred project. The Three Hundred consists of zoom re-simulations of 324 clusters with M200 ≳ 1014.8 M⊙ drawn from the MultiDark-Planck N-body simulation, run using several hydrodynamic and semi-analytic codes. The Gizmo-Simba suite adds a state-of-the-art galaxy formation model based on the highly successful Simba simulation, mildly re-calibrated to match z = 0 cluster stellar properties. Comparing to The Three Hundred zooms run with Gadget-X, we find intrinsic differences in the evolution of the stellar and gas mass fractions, BCG ages, and galaxy colour-magnitude diagrams, with Gizmo-Simba generally providing a good match to available data at z ≈ 0. Gizmo-Simba’s unique black hole growth and feedback model yields agreement with the observed BH scaling relations at the intermediate-mass range and predicts a slightly different slope at high masses where few observations currently lie. Gizmo-Simba provides a new and novel platform to elucidate the co-evolution of galaxies, gas, and black holes within the densest cosmic environments.

The distribution of baryons provides a significant way to understand the formation of galaxy clusters by revealing the details of its internal structure and changes over time. In this paper, we present theoretical studies on the scaled profiles of physical properties associated with the baryonic components, including gas density, temperature, metallicity, pressure and entropy as well as stellar mass, metallicity and satellite galaxy number density in galaxy clusters from z = 4 to z = 0 by tracking their progenitors. These mass-complete simulated galaxy clusters are coming from The Three Hundred with two runs: Gizmo-SIMBA and Gadget-X. Through comparisons between the two simulations, and with observed profiles which are generally available at low redshift, we find that (1) the agreements between the two runs and observations are mostly at outer radii r ≳ 0.3r500, in line with the self-similarity assumption. While Gadget-X shows better agreements with the observed gas profiles in the central regions compared to Gizmo-SIMBA; (2) the evolution trends are generally consistent between the two simulations with slightly better consistency at outer radii. In detail, the gas density profile shows less discrepancy than the temperature and entropy profiles at high redshift. The differences in the cluster centre and gas properties imply different behaviours of the AGN models between Gadget-X and Gizmo-SIMBA, with the latter, maybe too strong for this cluster simulation. The high-redshift difference may be caused by the star formation and feedback models or hydrodynamics treatment, which requires observation constraints and understanding.
