Laboratory Session VI



1. The Kuijken-Dubinski Galaxy Modeling Package

We will use the code of Konrad Kuijken and John Dubinski to generate disk-bulge-halo galaxies. The method is described in this paper .

The complete source package (mostly f77) is in the tar file galactics.tar.gz .

  • Getting the source and unpacking (no pgplot in tar file)

  • Create directory tree galaxy: gunzip -d -c galaxy.tar.gz | tar xvf -

  • in csh type: setenv LD_LIBRARY_PATH /software/physics/lib
  • in csh type: setenv _POSIX2_VERSION 199209
  • in bash type: export LD_LIBRARY_PATH=/software/physics/lib
  • in bash type: export _POSIX2_VERSION=199209

    read the README file

  • Using the Makefile:

  • make all

  • make galaxy

    •  First test of the BULGE

  • We will use the data file bulge.data to run the Aarseth code with it.

  • Visualization with DX

    •  First test of the HALO

  • We will use the data file halo.data to run the Aarseth code with it.

  • Visualization with DX

    •  First test of the DISK

  • We will use the data file disk.data to run the Aarseth code with it.

  • Visualization with DX

    •  First test of the complete GALAXY

  • We will use the data file galaxy.data to run the Aarseth code with it.

  • Visualization with DX
