Abstract:We introduce the TangoSIDM project, a suite of cosmological simulations of structure formation in a Ξ-Self-Interacting Dark Matter (SIDM) universe. TangoSIDM explores the impact of large dark matter (DM) scattering cross sections over dwarf galaxy scales. Motivated by DM interactions that follow a Yukawa potential, the cross section per unit mass, π/π π , assumes a velocity dependent form that avoids violations of current constraints on large scales. We demonstrate that our implementation accurately models … Show more
