Simulating the LOcal Web (SLOW) -- III: Synchrotron emission from the local cosmic web

Understand

Aims: Detecting diffuse synchrotron emission from the cosmic web is still a challenge for current radio telescopes.

• We aim to make predictions about the detectability of cosmic web filaments from simulations.
• Methods: We present the first cosmological magnetohydrodynamic simulation of a 500 $h^{-1} c$Mpc volume with an on-the-fly spectral cosmic ray (CR) model.
• This allows us to follow the evolution of populations of CR electrons and protons within every resolution element of the simulation.
