    Are Long GRBs caused by PopIII hypernovae?

    Diversity of the Supernova - Gamma-Ray Burst Connection by Nomoto, Tominaga, Tanaka, Maeda, Suzuki, Deng, and Mazzali. To be published in the proceedings of the conference “SWIFT and GRBs: Unveiling the Relativistic Universe”, Venice, June 5-9, 2006. To appear in “Il Nuovo Cimento”
    See the diagram of such a jet-induced hypernova:

    Interesting question. It prompted me to look at some other papers - and there is much at which to look.

    A new constraint for gamma-ray burst progenitor mass

    This last point is rather interesting.

    Are PopIII hypernovae distributed similarly to LGRBs?

    Are there LGRBs without PopIII hypernovae - e.g. Hybrid GRB 060614?

    Here is a page on GRB030329 - http://wise-obs.tau.ac.il/GRB030329/

    And then there is - GRB 060218 - http://arxiv.org/abs/astro-ph/0701804

    Interesting. I perceive SM black holes must be primordial events - i.e., they do no evolve from progenitor stars. The time line is far too short to lend credibility to this theory - IMO.
