Query: Active velocity processes with suprathermal stationary distributions and
  long-time tails   When a particle moves through a spatially-random force field, its momentum
may change at a rate which grows with its speed. Suppose moreover that a
thermal bath provides friction which gets weaker for large speeds, enabling
high-energy localization. The result is a unifying framework for the emergence
of heavy tails in the velocity distribution, relevant for understanding the
power-law decay in the electron velocity distribution of space plasma or more
generally for explaining non-Maxwellian behavior of driven gases. We also find
long-time tails in the velocity autocorrelation, indicating persistence at
large speeds for a wide range of parameters and implying superdiffusion of the
position variable.
