  text: We use numerical simulations to compute the equation of state of a suspension
    of spherical self-propelled nanoparticles in two and three dimensions. We study
    in detail the effect of excluded volume interactions and confinement as a function
    of the system's temperature, concentration, and strength of the propulsion. We
    find a striking nonmonotonic dependence of the pressure on the temperature and
    provide simple scaling arguments to predict and explain the occurrence of such
    anomalous behavior. We explicitly show how our results have important implications
    for the effective forces on passive components suspended in a bath of active particles.
