Michael A. K. Gross Physics Dept. Particle-Mesh lectures , from the 1998 NASA High Performance Computational Physics Summer School Protected areas Ph.D. Dissertation To print a copy of my thesis, here are compressed and uncompressed versions. Everything is provided in both gzipped and uncompresed form. There have been some requests for the styles and macros used in this thesis. Useful cosmological tools These are Fortran-77 programs that calculate standard cosmological quantities in an arbitrary Friedmann cosmology.
All programs contain an accurate, extremely fast adaptive integrator.
This makes calculating a reasonably well-behaved integral very inexpensive, so integral formulations are used in place of less accurate fits or special cases. Age of the universe at a given expansion factor. Calculated by integrating the Friedmann equation. Linear fluctuation growth factor, normalized to be equal to the expansion parameter at early times. Calculated using the Wronskian integral formalism.
