Effective resistivity in relativistic reconnection: a prescription based on fully kinetic simulations
Abigail Moran, Lorenzo Sironi, Aviad Levis +3
A variety of high-energy astrophysical phenomena are powered by the release -- via magnetic reconnection -- of the energy stored in oppositely directed fields. Single-fluid resisti…
