DOI: 10.1093/mnras/stab2722
Abstract: The galaxy luminosity function and galaxy stellar mass function are fundamental statistics to test the galaxy formation models. Theoretical predictions based on cosmological simulations can deviate from observations, especially at bright and faint ends. In… read more here.

DOI: 10.1093/mnras/stab496
Abstract: The past decade has seen significant progress in understanding galaxy formation and evolution using large-scale cosmological simulations. While these simulations produce galaxies in overall good agreement with observations, they employ different sub-grid models for galaxies… read more here.

DOI: 10.1093/mnras/stad998
Abstract: Wave (fuzzy) dark matter ($\psi \rm {DM}$) consists of ultralight bosons, featuring a solitonic core within a granular halo. Here we extend $\psi \rm {DM}$ to two components, with distinct particle masses m and coupled… read more here.

DOI: 10.1093/mnras/stz2076
Abstract: We study influence by models of interstellar medium (ISM) on properties of galaxies in cosmological simulations. We examine three models widely used in previous studies. The ISM models impose different equations of state on dense… read more here.

DOI: 10.1093/mnrasl/sly190
Abstract: The circumgalactic medium (CGM), i.e. the gaseous haloes around galaxies, is both the reservoir of gas that fuels galaxy growth and the repository of gas expelled by galactic winds. Most cosmological, hydrodynamical simulations focus their… read more here.
