  • testing the Blast Wave model with swift grbs
    Monthly Notices of the Royal Astronomical Society, 2009
    Co-Authors: P. A. Curran, A. J. Van Der Horst, R. L. C. Starling, Ralph A. M. J. Wijers
    Abstract:

    The complex structure of the light curves of Swift Gamma-Ray Bursts (GRBs) has made the identification of breaks, and the interpretation of the Blast Wave caused by the burst, more difficult than in the pre-Swift era. We aim to identify breaks, which are possibly hidden, and to constrain the Blast Wave parameters; electron energy distribution, p, density profile of the circumburst medium, k, and the continued energy injection index, q. We do so by comparing the observed multiWavelength light curves and X-ray spectra of our sample to the predictions of the Blast Wave model. We can successfully interpret all of the bursts in our sample of 10, except two, within this framework and we can estimate, with confidence, the electron energy distribution index for 6 of the sample. Furthermore, we identify jet breaks in a number of the bursts. A statistical analysis of the distribution of p reveals that, even in the most conservative case of least scatter, the values are not consistent with a single, universal value. The values of k suggest that the circumburst density profiles are not drawn from only one of the constant density or wind-like media populations.

  • energy transfer from a laser pulse to a Blast Wave in reduced pressure air atmospheres
    Journal of Applied Physics, 2004
    Co-Authors: Koichi Mori, Kimiya Komurasaki, Yoshihiro Arakawa
    Abstract:

    Focusing a transversely excited atmospheric CO2 laser beam in air atmospheres induced a Blast Wave. The kinetic energy of a laser-induced Blast Wave was determined from shadowgraph images of shock Wave expansion. Results showed that the fraction of input laser energy that is converted into the Blast Wave energy decreased from 0.45 to 0.2 concomitant with the decrease in ambient pressure from 100 to 10 kPa. Also, it was insensitive to input laser energy from 4 to 13 J.Focusing a transversely excited atmospheric CO2 laser beam in air atmospheres induced a Blast Wave.
