The FLAMINGO project: cosmological hydrodynamical simulations for large-scale structure and galaxy cluster surveys [PDF]
Monthly notices of the Royal Astronomical Society, 2023 We introduce the Virgo Consortium’s FLAMINGO suite of hydrodynamical simulations for cosmology and galaxy cluster physics. To ensure the simulations are sufficiently realistic for studies of large-scale structure, the subgrid prescriptions for stellar ...

Hydrodynamical Simulations of the Galaxy Population: Enduring Successes and Outstanding Challenges [PDF]
Annual Review of Astronomy and Astrophysics, 2023 We review the progress in modeling the galaxy population in hydrodynamical simulations of the ΛCDM cosmogony. State-of-the-art simulations now broadly reproduce the observed spatial clustering of galaxies; the distributions of key characteristics, such ...

Comparison of Low-Redshift Lyman-α Forest Observations to Hydrodynamical Simulations with Dark Photon Dark Matter. [PDF]
Physical Review Letters, 2022 Recent work has suggested that an additional ≲6.9 eV per baryon of heating in the intergalactic medium is needed to reconcile hydrodynamical simulations with Lyman-α forest absorption line widths at redshift z≃0.1.

The probability of galaxy-galaxy strong lensing events in hydrodynamical simulations of galaxy clusters [PDF]
Astronomy & Astrophysics, 2022 Meneghetti et al. (2020) recently reported an excess of galaxy-galaxy strong lensing (GGSL) in galaxy clusters compared to expectations from the LCDM cosmological model. Theoretical estimates of the GGSL probability are based on the analysis of numerical

IQ Collaboratory. III. The Empirical Dust Attenuation Framework—Taking Hydrodynamical Simulations with a Grain of Dust [PDF]
Astrophysical Journal, 2021 We present the empirical dust attenuation (EDA) framework—a flexible prescription for assigning realistic dust attenuation to simulated galaxies based on their physical properties. We use the EDA to forward model synthetic observations for three state-of-

The galaxy size to halo spin relation of disc galaxies in cosmological hydrodynamical simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2021 In the standard disc galaxy formation model, the sizes of galactic discs are tightly related to the spin parameters λ of their dark matter haloes. The model has been wildly adopted by various semi-analytical galaxy formation models which have been ...

Low-surface-brightness Galaxies are Missing in the Observed Stellar Mass Function
The Astrophysical Journal, 2023 We investigate the impact of the surface-brightness (SB) limit on the galaxy stellar mass functions (GSMFs) using galaxy catalogs generated from the Horizon Run 5 ( HR5 ) simulation.

Massive disc galaxies in cosmological hydrodynamical simulations are too dark matter-dominated [PDF]
Astronomy & Astrophysics, 2020 We investigate the disc-halo connection in massive (Mstar/Msun>5e10) disc galaxies from the cosmological hydrodynamical simulations EAGLE and IllustrisTNG, and compare it with that inferred from the study of HI rotation curves in nearby massive spirals ...

Simulating self-gravitating hydrodynamic flows [PDF]
Computer Physics Communications, 1995 An efficient algorithm for solving Poisson's equation in two and three spatial dimensions is discussed. The algorithm, which is described in detail, is based on the integral form of Poisson's equation and utilizes spherical coordinates and an expansion into spherical harmonics.

Hydrodynamic simulations with the Godunov smoothed particle hydrodynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 We present results based on an implementation of the Godunov smoothed particle hydrodynamics (GSPH), originally developed by Inutsuka, in the gadget-3 hydrodynamic code. We first review the derivation of the GSPH discretization of the equations of moment and energy conservation, starting from the convolution of these equations with the interpolating ...
