Effective temperature and dissipation of a gas of active particles probed by the vibrations of a flexible membrane

We use a flexible circular membrane to probe a gas of macroscopic self-propelled rod-like robots. The fluctuations of the membrane are completely described by a set of discrete modes with different characteristic frequencies. We show that the dynamics of each mode can be well described by a Langevin...
