Parameters used to generate the ICs of the galaxy models used in the simulations.
| Galaxy | Mdm [109 M⊙] | a [kpc] | M⋆ [107 M⊙] | (h⋆, z⋆) [kpc] | (Re, sat [kpc], m) | MH I [107 M⊙] | hgas [kpc] |
|---|---|---|---|---|---|---|---|
| NGC 5238 | 3.44 | 2.07 | 8.9 | (0.52, 0.052) | – | 2.74 | 0.52 |
| Satellite | 0.3 | 0.99 | 0.02 | (0.15, 0.015) | – | 0.015 | 0.3 |
| UGC 8760 | 1.91 | 1.87 | 2 | (0.275, 0.028) | – | 2.64 | 0.55 |
| Satellite | 0.15 | 0.5 | 0.06 | – | (0.15, 0.75) | – | – |
Notes. Mdm and a are the dark-matter mass and scale radius (Eqs. (1) and (12)); if the stellar component is a disc, then M⋆, h⋆ and z⋆ are the total stellar mass, scale length and scale height of the disc, respectively (Eq. (2)); otherwise M⋆, Re, sat and m are the total stellar mass, the effective radius and the Sérsic index of the corresponding Sérsic model, respectively (Eq. (13)). hgas is the gas disc scale length (Eq. (3)), MH I is the H I mass and the Helium mass (MHe) is always 0.35 MH I.
