Did "Dark Matter" Create the First Stars?

Did "Dark Matter" Create the First Stars?

Dark matter could be "sterile" neutrinos, whose decay led to the
formation of stars in the early universe

Dark matter may have played a major role in creating stars at the
very beginnings of the universe. If that is the case, however, the
dark matter must consist of particles called "sterile neutrinos".
Peter Biermann of the Max Planck Institute for Radio Astronomy in
Bonn, and Alexander Kusenko, of the University of California, Los
Angeles, have shown that when sterile neutrinos decay, it speeds up
the creation of molecular hydrogen. This process could have helped
light up the first stars only some 20 to 100 million years after the
big bang. This first generation of stars then ionised the gas
surrounding them, some 150 to 400 million years after the big bang.
All of this provides a simple explanation to some rather puzzling
observations concerning dark matter, neutron stars, and antimatter
(Physical Review Letters, March 10, 2006).
