Seminar

Halo concentration, assembly bias, and galaxy-halo connection

The connection between dark matter halos and galaxies is one of the most critical questions in galaxy formation. With new suites of cosmological simulations and zoom-in simulations of Milky Way-mass halos, we inspect the theoretical framework of the galaxy-halo connection. Particularly, in this talk I will discuss how to parametrize and to constrain the concentration dependence in the abundance matching technique, and the implications of this new parameter on assembly bias.
