Query: Fluctuations of rotational and translational degrees of freedom in an
  interacting active dumbbell system   We study the dynamical properties of a two-dimensional ensemble of
self-propelled dumbbells with only repulsive interactions. After summarizing
the behavior of the translational and rotational mean-square displacements in
the homogeneous phase that we established in a previous study, we analyze their
fluctuations. We study the dependence of the probability distribution functions
in terms of the P\'eclet number, describing the relative role of active forces
and thermal fluctuations, and of particle density.
