Theoretical Interpretation of Grb 011121

On the 21 November 2001 at 18:47:21 UT, GRB 011121 was observed by BeppoSAX satellite [1]. The localization was then refined by the Interplanetary Network [2] and an optical transient was identified by the OGLE group [3]. Spectroscopic measurements revealed some emission lines at the redshift z = 0.36 [4]. GRB 011121 is a long burst with T90 = 28 s; the fluence [5] is 2.4 × 10 −5 erg/cm that co...

Towards a Group-theoretical Interpretation of Mechanics

We argue that the classical description of a symplectic manifold endowed with a Hamiltonian action of an abelian Lie group G and the corresponding quantum theory can be understood as different aspects of the unitary representation theory of G. To do so, we propose a conceptual analysis of formal tools coming from symplectic geometry (notably, Souriau’s moment map and the Mardsen-Weinstein sympl...

Algorithm of the First Pass Algorithm of the Second Pass Figure 7 : Parameter Values for Approximation of Theoretical Functions

Picture 1, 2 and 3 show diierent views of a volume density object simulating a cloud illuminated by a single source. The cloud is deened by a 65 65 10 grid. The pictures were computed on a Sun SparcStation and visualized on a Silicon Graphics Personal Iris at a 400 400 resolution. For the rst pass, 2 million rays have been sent and the CPU time ranged from 3 to 4 minutes. For the second pass, 1...

Theoretical Interpretation of Luminosity and Spectral Properties of Grb 031203

The X and γ-ray observations of the source GRB 031203 by INTEGRAL are interpreted within our theoretical model. In addition to a complete space-time parametrization of the GRB, we specifically assume that the afterglow emission originates from a thermal spectrum in the co-moving frame of the expanding baryonic matter shell. By determining the two free parameters of the model and estimating the ...
