However, the nonlinear effects have no bearing on the ICM, which also requires DM to explain why it hasn't evaporated into intercluster space.

I've gotten the energy density for black body radiation for a given temperature. And we have the Unruh temperature for a given acceleration. But in order to apply this Unruh temperature to the acceleration due to gravity (as required by the equivalence principle. Is this DM) I need to calculate the emount of acceleration at each point for a given mass distribution. I could try to use the inverse square law, but this goes to infinity at r=0. And points in the second iteration would then be inside the new distribution when calculating second order effects. So does anyone have a formula for the acceleration felt by test particles calculated by using the gravitational potential for a given arbitrary mass density formula? Thanks.

Isn't this calculation worth doing for its own sake? If the Unruh effect of acceleration can be applied to gravitationally accelerated reference frames due to the equivalence principle, then should we try to see how much of an effect this would have?
