The physical origin of the universal function that describes the accretion history of dark matter haloes

Understanding the universal accretion history of dark matter haloes is the first step towards determining the origin of their structure. Previous studies have quantified halo mass accretion histories using catalogues of halos from numerical simulations, in this work (Correa C. A., Wyithe J. S. B., Schaye J., Duffy A. R., 2015a, MNRAS, 450, 1514) we […]

The connection between the mass power spectrum and the density profile of dark matter halos

Dark matter halos provide the potential wells inside which galaxies form. As a result, understanding their basic properties, including their formation history and internal structure, is an important step for understanding galaxy evolution. In this work (Correa C. A., Wyithe J. S. B., Schaye J., Duffy A. R., 2015b, MNRAS, 450, 1521) we explore the […]
