Description
Recently, it has been proposed that self-annihilating dark matter could have a
significant effect on the formation and development of the first stars in
the universe. In such a model, the energy from self-annihilation of dark matter particles
may be the main power source for this class of young stellar objects
called Dark Stars (DS). Their features (e.g. luminosity, temperature, lifetime)
differ from normal POP III stars and therefore makes them distinguishable.
The contribution of DS to the extragalactic background light considering multiple
initial parameters is calculated. By comparing our results with existing data
of the EBL we can derive first observational limits on Dark Stars in the early universe.
Future observations will improve these constraints.
