Brief resume

Research interest

In my research I study the influence of the cosmological constant corresponding to
accelerated expansion of the Universe on an optical effects in the vicinity of compact objects
such as black holes, naked singularities and eventually neutron stars. These effects include,
e. g., a shape of the light escape cones and related silhouettes of the gravitating bodies on a
bright cosmic background, self-illumination of an orbiting light source and the induced light
