Quantifying Kinematic Substructure in the Milky Way's Stellar Halo
Xiang-Xiang Xue, Hans-Walter Rix, Brian Yanny +13
We present and analyze the positions, distances, and radial velocities for over 4000 blue horizontal-branch (BHB) stars in the Milky Way's halo, drawn from SDSS DR8. We search for…
Modelling the dynamical friction timescale of sinking satellite
Jianling Gan, Xi Kang, Jinliang Hou +1
When a satellite galaxy falls into a massive dark matter halo, it suffers the dynamical friction force which drag it into the halo center and finally it merger with the central gal…
An Improved Model for the Dynamical Evolution of Dark Matter Subhaloes
JianLing Gan, Xi Kang, Frank C. van den Bosch +1
Using an analytical model, we study the evolution of subhalo, including its mass, angular momentum and merging time-scale. This model considers the dominant processes governing sub…
The dependence of AGN activity on stellar and halo mass in Semi-Analytic Models
Fabio Fontanot, Anna Pasquali, Gabriella De Lucia +3
AGN feedback is believed to play an important role in shaping a variety of observed galaxy properties, as well as the evolution of their stellar masses and star formation rates. In…
Galaxy formation with cold gas accretion and evolving stellar initial mass function
Xi Kang, WeiPeng Lin, Ramin A. Skibba +1
The evolution of the galaxy stellar mass function is especially useful to test the current model of galaxy formation. Observational data have revealed a few inconsistencies with pr…
