On scattering of CMB radiation on wormholes: kinetic SZ-effect |
|
Abstract |
The problem of scattering of CMB radiation on a wormhole is considered. It is shown that a static gas of wormholes does not perturb the spectrum of CMB. In the first order by $v/c$ the presence of peculiar velocities gives rise to the dipole contribution in $\Delta T/T$, which corresponds to the well-known kinetic Sunaev-Zeldovich effect. In next orders there appears a more complicated dependence of the perturbed CMB spectrum on peculiar velocities. |
