Towards a New Theory of Cosmic Ray Origin tycho


The theory that cosmic rays originate from massive stars that explode to give Gamma Ray Bursts and Fireball Transients is proposed in the submission (astro-ph/0005440) entitled
  • Neutrino, Neutron, and Cosmic Ray Production in the External Shock Model of Gamma Ray Bursts, which is submitted to The Astrophysical Journal.

    A presentation on this subject, given at the Naval Research Laboratory (06/14), Ruhr University Bochum (06/23), the Heidelberg Gamma 2000 Workshop (06/27), NASA/GSFC (07/18), the California Institute of Technology (08/11), and Worcester Polytechnic Institute (11/13) is available here:

  • Gamma Ray Bursts and the Origin of the Cosmic Radiation (Powerpoint presentation, 11.1 MB)

    A calculation of the available power from Gamma Ray Bursts and Fireball Transients was presented at the Second Rome Workshop on Gamma Ray Bursts in the Afterglow Era (17-20 October 2000). It is given in the submission (astro-ph/0010564) entitled

  • Gamma Ray Bursts, Cosmic Ray Origin, and the Unidentified EGRET Sources. Here I show that there is sufficient power in massive stars that collapse to form black holes to power the ultra-high energy cosmic rays, the cosmic rays above the knee and, indeed, all hadronic cosmic rays observed locally. A shortened version will appear in the Proceedings of the Heidelberg 2000 High-Energy Gamma-Ray Workshop, ed. F. A. Aharonian and H. Völk (AIP: New York)

    Second-order Fermi acceleration in relativistic blast waves is shown to be capable of accelerating particles to ultra-high energy in the Astrophysical Journal submission (astro-ph/0010564) entitled

  • Adiabatic Losses and Ultra-High Energy Cosmic Ray Acceleration in Gamma-Ray Burst Blast Waves , by Mayer Humi (Worcester Polytechnic Institute) and myself. Here we also consider competing adiabatic and synchrotron losses in the expanding blast waves.

    The difficulties of first-order shock Fermi acceleration to accelerate cosmic ray protons and ions to and past the knee of the cosmic ray spectrum is presented in the paper (astrop-ph/12490) entitled

  • Maximum Particle Energy by Fermi Acceleration in Relativistic Flows , submitted to Astrophysical Journal Letters.

    Other features of this theory of cosmic-ray origin will be posted here in the near future, including answers to criticisms made at the Heidelberg Workshop.
