Chemical and Photometric Evolution Models for Disk, Irregular, and Low Mass Galaxies

Figure 5

Evolution with redshift of the surface density of diffuse gas, Σ_HI, molecular gas, Σ_H2, and stellar mass, Σ_∗, in M_⊙pc⁻², in top, middle-top, and middle-bottom rows, and the star formation rate, Ψ, in M_⊙Gyr⁻¹pc⁻², in the bottom one. All in logarithmic scale. Each column shows the results for a theoretical galaxy of the Table 1, from the galaxy, with 𝑉_max=78kms⁻¹, to the most massive one for 𝑉_max=290kms⁻¹. Each line corresponds to a different redshift: purple, blue, cyan, green, magenta, orange, and red for 𝑧=5, 4, 3, 2, 1, 0.4, and 0, respectively.
