Query: The vacuum energy excitations due to gravitational field as a possible
  candidate of dark matter in galaxies   In this Letter we point out to the possibility that the cloud of the vacuum
energy excitations in gravitation fields surrounding galaxies forms a component
of dark matter. These clouds of the vacuum energy excitations interact
gravitationally with the baryonic matter of galaxies changing their dynamical
and kinematical properties. In four model galaxies we show that the dynamic
changes due to the vacuum energy excitations of these galaxies are comparable
with data. This shows that vacuum energy excitations created in the gravitation
field of galaxies may be considered as one of the candidates of dark matter.
