Vacuum Polarization Instead of “Dark Matter” in a Galaxy

We considered a vacuum polarization inside galaxy in the eikonal approximation and found that two possible types of exist. The first type is described by equation state p=ρ/3, similar to radiation. Using conformally unimodular metric allows us construct non-singular solution for this “substance” if compact astrophysical object exists galaxy’s center. As result, “dark” galactical halo appears increases rotation velocity test particle as function distance from galactic second has more complicated state. static physical effect, it produces renormalization gravitational constant, thus, causing no halo. However, non-stationary type, resulting an exponential increase (or decrease) nuclei mass with time some hypothetical time-dependent process, potential, appearing dark matter
