Galaxy populations in groups and clusters-II. Conditional luminosity functions at redshifts from z~1 to z~0
Ce Gao, Cheng Li, Houjun Mo +5
Using DESI SV3 spectroscopic group centrals and HSC photometric data, we measure conditional luminosity functions (CLFs) of central and satellite galaxies for red and blue populati…

Connection between galaxy morphology and dark-matter halo structure II: predicting disk structure from dark-matter halo properties
Jinning Liang, Fangzhou Jiang, Houjun Mo +4
We investigate how galactic disk structures connect to the detailed properties of their host dark-matter halos using the TNG50 simulation. From the hydrodynamic and matched dark-ma…

Connection between galaxy morphology and dark-matter halo structure I: a running threshold for thin discs and size predictors from the dark sector
Jinning Liang, Fangzhou Jiang, Houjun Mo +5
We study the connection between galaxy morphology and host dark matter (DM) halo structure using cosmological simulations. Introducing a new kinematic decomposition scheme, we robu…
