Abstract
We study numerically a model of self-propelled polar disks in suspension. The active particles interact via hardcore elastic interactions and are driven along their axes, which are subject to rotational noise. We study the distribution of linear and rotational velocities, which are predicted to show strongly anomalous but largely universal features. We furthermore study the motion of particles in the presence of immobile obstacles and show that activity enhances diffusion in heterogeneous media.
