National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Simulation of Cosmic Ray Acceleration, Propagation and Interaction in SNR Environment.

DE2007918043

Publication Date	2007
Personal Author	Lee, S. H.; Kamae, T.; Ellison, D. C.
Page Count	2
Abstract	This work aims to develop a highly flexible platform for 3D SNR hydro and cosmic ray (CR) simulation, which is easily expandable to accept new physics, and adaptable to the complex environments of individual supernova remnants. As a preliminary work in progress, the simulation is tested under toy model configurations, in a cubic mesh with a relatively low resolution (21x21x21 binning). Several assumptions and simplifications are made in the physics of cosmic ray acceleration and diffusion. Once the framework becomes mature, however, we can immediately proceed to perform realistic modeling of any given SNR, match in broad-band with observations, and extract useful information.
