How well is angular momentum accretion modelled in semi-analytic galaxy formation models?
Jun Hou, Cedric G. Lacey, Carlos S. Frenk
Gas cooling and accretion in haloes delivers mass and angular momentum onto galaxies. In this work, we investigate the accuracy of the modelling of this important process in severa…
A comparison between semi-analytical gas cooling models and cosmological hydrodynamical simulations
Jun Hou, Cedric G. Lacey, Carlos. S. Frenk
We compare the mass cooling rates and cumulative cooled-down masses predicted by several semi-analytical (SA) cooling models with cosmological hydrodynamical simulations performed…
A new gas cooling model for semi-analytical galaxy formation models
Jun Hou, Cedric G. Lacey, Carlos. S. Frenk
Semi-analytic galaxy formation models are widely used to gain insight into the astrophysics of galaxy formation and in model testing, parameter space searching and mock catalogue b…
Constraining SN feedback: a tug of war between reionization and the Milky Way satellites
Jun Hou, Carlos. S. Frenk, Cedric G. Lacey +1
Theoretical models of galaxy formation based on the cold dark matter cosmogony typically require strong feedback from supernova (SN) explosions in order to reproduce the Milky Way…
Probing baryonic processes and gastrophysics in the formation of the Milky Way dwarf satellites: I. metallicity distribution properties
Jun Hou, Qingjuan Yu, Youjun Lu
In this paper, we study the chemical properties of the stars in the dwarf satellites around the MW-like host galaxies, and explore the possible effects of several baryonic processe…
