ASTROPHYSICS

We have implemented the following patterns

RANDOM WALK-->Simulation of images through the random walk

SPIRALS-->Simulation of spiral galaxies through the percolation

SPIRALS IN INTERACTION-->Spiral galaxy in gravitational interaction

Asymmetric SNR -->Evolution of SNR in a asymmetric medium

RANDOM WALK

The random walk from many injection points allow to simulate the images of various astrophysical objects paper. We report some examples:

1. Diffusion from the centre in 2D
2. Simulation HH34
3. Simulation of symmetric SNR
4. Radio-map of Casa-A

SPIRALS IN INTERACTION

Combining the evolution of a N-body ensemble with the percolation theory we can simulate the spiral galaxies in interaction paper.

Asymmetric SNR

In order to attack the problem of asymmetric shapes of the observed Supernova Remnants, a numerical technique is developed that divides the sphere into many sectors. Using this numerical method, some of the observed features of the supernova remnants, like a barrel shape or multi-ring shape can be reproduced paper.
