Computing

  • Allocation on Frontera ends on Dec. 31
  • Storage
    • We have already exceded our storage on Ranch but they have moved most of it to tape to free up space for us. So we have almost 200 TB available.
  • Parallel HDF5
    • Debugging with Jonathan and Baowei

EOS Runs

  • Analyzed unbound mass comparing EOS Run 271 to old fiducial Run 143.
  • Ongoing Runs (Trying to optmize parameter values for final production run)
    • Run 273: ambient density reduced from 6.7e-9 g/cm3 to 1e-9 g/cm3
    • Run 274: RGB core particle mass equals m(r_soft) of original profile (skipping iteration over particle mass)

Next steps

  • Analyze energy conservation for runs 273 and 274
  • Analyze peak density for runs 271, 273 and 274
  • Compute ambient unbound mass and subtract from total (as Amy has now done for jet runs)
  • Make 2D slices (to compare) of:
    1. Mass density of Ionization state tracer (tracing gas with a given ionization state at t=0)
    2. Mass density of Ionization state (actual ionization state at time t)
  • Compute total recombination energy of each species (e.g. HII, HeIII) as a function of time
  • Compute total recombination energy of each species (e.g. HII, HeIII) as a function of time for bound and unbound mass separately
    • This will tell us whether recombination energy is being released into bound gas (where it can be "useful") vs. unbound gas (where it cannot), c.f. Fig. 1 of Paper II
  • Some version of Figs. 9 and 10 of Paper IV that includes recombination energy
