Abstract

We measure the signal of secondary halo bias as a function of a variety of intrinsic and environmental halo properties, and characterize its statistical significance as a function of cosmological redshift. Using fixed and paired N-body simulations of dark-matter halos -- the UNIT simulation -- with masses above 10¹¹M_\odoth^-1 identified over a wide range of cosmological redshifts (0
