摘要：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 released by the self-annihilating dark matter may be the main power source for this class of young stellar objects called Dark Stars (DS). Their features (e.g. luminosity, temperature, lifetime) could differ from normal PopIII stars and therefore makes them distinguishable. The contribution of DS to the extragalactic background light (EBL) considering multiple initial parameters is calculated. By comparing our results with existing EBL data and limits we can derive first observational constraints on Dark Stars in the early universe. Future observations (e.g. with JWST) will improve these results.
