Abstract
In the case of no-horizon regular spacetimes there exist a region close to origin where the spacetime is “flattened”. Existence of such a region leads to presence of so called “ghost” images of accretion discs orbiting in the spacetimes. We show how the presence of the ghost images influences distribution of photons in the profiles of spectral lines generated by Keplerian disks.
