Beasts in Lambda-CDM Zoo
  Recent astronomical discoveries of supermassive black holes (quasars),
gamma-bursters, supernovae, and dust at high redshifts, z = (5 --10), are
reviewed. Such a dense population of the early universe is at odds with the
conventional mechanisms of its possible origin. Similar data from the
contemporary universe, which are also in conflict with natural expectations,
are considered too. Two possible mechanisms are suggested, at least one of
which can potentially solve all these problems. As a by-product of the last
model, an abundant cosmological antimatter may be created.
