Observations of astrophysical objects which cannot exist.

Prof. Alexander Dolgov (FE)

Recently astronomical data are accumulated, reporting discoveries of very early formed objects, such as supermassiveblack holes (quasars), gamma bursters,
supernovae, and very bright galaxies at high redshifts. Moreover, there is an evidence to existence of starts in our Galaxy which are too old, even older than the
universe. All such objects cannot be created in the frameworks of accepted scenarios of their formation. An origin of supermassive black holes observed in the
centers of many (maybe all) large and some small galaxies also remains mysterious.

After a review of the observations a model is presented that can explain the unusual features of the data. The model is based on a slightly modified scenario of baryogenesis motivated by supersymmetry. As a byproduct the model can predict abundant cosmological antimatter, in particular almost at hand, in the Galaxy.

Though the model may be rather speculative, the observed objects present serious challenge to the theory and possibly indicate that “there is something rotten in the state of the universe”
