abstract

  • We intend to make sets of cosmological simulations available, with a large number of different output times that may be placed side-by-side to produce a complete history of the universe stretching back to high redshift. Currently there is only one series of runs under preparation as a trial. Gauging by the response, we will consider further releases. The first series consists of N-body simulations with CDM-like spectra (Gamma=0.25) in a 100/h Mpc box, in three different cosmologies: Einstein-de Sitter, low-density flat and low-density open. The parameters of each run are: 1) Run 501: Omega=1.0, lambda=0.0, sigma_8=0.64. N=128**3. 38 time-slices back to z=5.8 (a further 11 back to z=23.4 on request). 2) Run 502: Omega=0.3, lambda=0.7, sigma_8=1.22. N=86**3. 49 time-slices back to z=3.6. 3) Run 503: Omega=0.3, lambda=0.0, sigma_8=1.06. N=86**3. 49 time-slices back to z=6.2 Check out our Web pages for more details: http://coho.astro.uwo.ca/pub/consort.html
