Dark Matter Halo Mass Profiles

Abstract

I provide notes on the NFW, Einasto, Sersic, and other mass profiles which provide good fits to simulated dark matter halos (S3). I summarize various published c(M) relations: halo concentration as a function of mass (S1). The definition of the virial radius is discussed and relations are given to convert c_vir, M_vir, and r_vir between various defined values of the halo overdensity (S2).
