My understanding is that the gas physics model of Illustris does not incorporate physical conductivity, but it does incorporate an artificial conductivity term.
Would it be possible to quantify the artificial conductivity term as a fraction of the Spitzer conductivity (e.g., artificial conductivity is roughly equivalent to 1/10 of the Spitzer conductivity)?
Thank you.

There is no explicit artificial conductivity -- these simulations are run with AREPO, which is not a SPH code.
There are of course numerical viscosity and diffusion types effects at the grid (resolution) scale, but I don't think this is what you mean?
