Athanassoula, Francesca Iannuzzi","submitted_at":"2013-08-30T19:00:50Z","abstract_excerpt":"Dynamical simulations are a fundamental tool for studying the secular evolution of disc galaxies. Even at their maximum resolution, they still follow a limited number of particles and typically resolve scales of the order of a few tens of parsecs. Generally, the spatial resolution is defined by (some multiple of) the softening length, whose value is set as a compromise between the desired resolution and the need for limiting small-scale noise. Several works have studied the question whether a softening scale fixed in space and time provides a good enough modelling of an astrophysical system.
