Can tides disrupt cold dark matter subhaloes?

4 Jun 2019Raphaël ErraniJorge Peñarrubia

The clumpiness of dark matter on sub-kpc scales is highly sensitive to the tidal evolution and survival of subhaloes. In agreement with previous studies, we show that N-body realisations of cold dark matter subhaloes with centrally-divergent density cusps form artificial constant-density cores on the scale of the resolution limit of the simulation...
