(Pre-Course Assignment)

Download, compile and run the Big Bang Nucleosynthesis Code

  1. Download the Big Bang Nucleosynthesis Code.
  2. Compile the code with your fortran90 compiler.
  3. Report in the Reaction Network Code discussion thread your success with machine information.
  4. Generate light element abundance predictions for a range of initial baryon-to-photon ratios, $\eta$.
    • Create the “Schramm Plot”Schramm Plot: Please note that these lines have a finite thickness. This thickness denotes the uncertainties from nuclear reaction rates, propagated into the abundance predictions.
  5. Repeat with $N_\nu = 2$ and $4$.
