My calculated HI density fraction from a Galform sub-volume is orders of magnitude too small. What am I missing?
Summary The issue at hand is that the calculated HI density fraction from a Galform sub-volume is orders of magnitude too small. The expected value of average Ω_HI is around 3-5e-4 for z = 0, but the current calculation yields a value of approximately 3e-7. The code provided seems to conserve mass during the gridding … Read more
