HI disc properties

Table listing the properties of HI discs in the Auriga simulations (adapted from Marinacci et al. 2016). The columns show (from left to right):

  • simulation name;
  • HI radius (L08)*;
  • HI mass (L08);
  • average HI surface density (L08);
  • HI scale height (L08);
  • HI gas fraction (L08);
  • HI radius (GK11)†;
  • HI mass (GK11);
  • average HI surface density (GK11);
  • HI scale height (GK11);
  • HI gas fraction (GK11).

*L08 = Leroy et. al (2008) method to compute the H2 fraction.
†GK11 = Gnedin & Kravtsov (2011) method to compute the H2 fraction.
