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…
Universality in the stress tensor for Holographic fluids at the finite cutoff surface via fluid/gravity correspondence
Ya-Peng Hu, Xin-Meng Wu, Jun-Peng Hou +1
We investigate the stress tensor for holographic fluids at the finite cutoff surface through perturbing the Schwarzchild-AdS black brane background to the first order perturbations…
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…
Reionisation in sterile neutrino cosmologies
Sownak Bose, Carlos S. Frenk, Hou Jun +2
We investigate the process of reionisation in a model in which the dark matter is a warm elementary particle such as a sterile neutrino. We focus on models that are consistent with…
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…
Perihelion precession and deflection of light in the general spherically symmetric spacetime
Ya-Peng Hu, Hongsheng Zhang, Jun-Peng Hou +1
In this paper, the perihelion precession and deflection of light have been investigated in the 4-dimensional general spherically symmetric spacetime, and the main equation is obtai…
