Abstract
In the present paper we consider the Type-2.x and Type-3.x extraterrestrial
von- Neumann probes and study the problem of their detectability by the
world's largest single-dish radio telescope: the Five-hundred-meter Aperture
Spherical Radio Telescope (FAST). For this purpose we estimate the radio
spectral parameters and analyse the obtained results in the context of
technical characteristics of FAST. As a result, it is shown that FAST can
detect both the galactic and extragalactic self-replicating probes with high
precision.
期刊介绍：
Serbian Astronomical Journal publishes original observations and researches in all branches of astronomy. The journal publishes:
Invited Reviews - review article on some up-to-date topic in astronomy, astrophysics and related fields (written upon invitation only),
Original Scientific Papers - article in which are presented previously unpublished author''s own scientific results,
Preliminary Reports - original scientific paper, but shorter in length and of preliminary nature,
Professional Papers - articles offering experience useful for the improvement of professional practice i.e. article describing methods and techniques, software, presenting observational data, etc.
In some cases the journal may publish other contributions, such as In Memoriam notes, Obituaries, Book Reviews, as well as Editorials, Addenda, Errata, Corrigenda, Retraction notes, etc.
