SatGen: a semi-analytical satellite galaxy generator -- I. The model and its application to Local-Group satellite statistics
Fangzhou Jiang, Avishai Dekel, Jonathan Freundlich +5
We present a semi-analytic model of satellite galaxies, SatGen, which can generate large samples of satellite populations for a host halo of desired mass, redshift, and assembly hi…
A new calibration method of sub-halo orbital evolution for semi-analytic models
Shengqi Yang, Xiaolong Du, Andrew J. Benson +2
Understanding the non-linear dynamics of satellite halos (a.k.a. "sub-halos") is important for predicting the abundance and distribution of dark matter substructures and satellite…
Constraints on the mass-concentration relation of cold dark matter halos with 11 strong gravitational lenses
Daniel Gilman, Xiaolong Du, Andrew Benson +3
The mass-concentration relation of dark matter halos reflects the assembly history of objects in hierarchical structure formation scenarios, and depends on fundamental quantities i…
Warm dark matter chills out: constraints on the halo mass function and the free-streaming length of dark matter with 8 quadruple-image strong gravitational lenses
Daniel Gilman, Simon Birrer, Anna Nierenberg +3
The free-streaming length of dark matter depends on fundamental dark matter physics, and determines the abundance and concentration of dark matter halos on sub-galactic scales. Usi…
