Stars and black holes from the very early universe

A mechanism of the creation of stellarlike objects in the very early universe, from the QCD phase transition until big bang nucleosynthesis and somewhat later, is studied. It is argued that in the considered process, primordial black holes with masses above a few solar masses up to superheavy ones could be created. This may explain an early quasar creation with evolved chemistry in surrounding medium and the low mass cutoff of the observed black holes. It is also shown that dense primordial stars can be created at the considered epoch. Such stars could later become very early supernovae and, in particular, high redshift gamma bursters. In a version of the model, some of the created objects can consist of antimatter.
