Abstract: Abstract Observations indicate that several types of astrophysical sources produce relativistic jets that interact with the intergalactic medium, creating regions of counterstreaming plasma. Under these conditions the plasma is susceptible to filamentation instabilities. Analytical analysis of this environment is highly non-trivial, which leads to the extensive use of computer simulations to study these conditions and the connection to the energetic photons and particles emanating from these sources. To make simulations feasible one has to make a couple of simplifications to reduce the computational complexity to a level that is reachable with todays computers. One such simplification is the reduction of the proton mass compared to the electron mass. This project tries to assess what the lower limit of this quantity is that still allows a realistic representation of the situation in nature.
