Query: Thermal-inertial effects on magnetic reconnection in relativistic pair
  plasmas   The magnetic reconnection process is studied in relativistic pair plasmas
when the thermal and inertial properties of the magnetohydrodynamical fluid are
included. We find that in both Sweet-Parker and Petschek relativistic scenarios
there is an increase of the reconnection rate owing to the thermal-inertial
effects, both satisfying causality. To characterize the new effects we define a
thermal-inertial number which is independent of the relativistic Lundquist
number, implying that reconnection can be achieved even for vanishing
resistivity as a result of only thermal-inertial effects. The current model has
fundamental importance for relativistic collisionless reconnection, as it
constitutes the simplest way to get reconnection rates faster than those
accessible with the sole resistivity.
