The atomic gas sequence and mass-metallicity relation from dwarfs to massive galaxies

Paper link: Scholte et al. (2024)

Atomic gas sequence

Our measurements of the atomic gas fraction of galaxies are listed below (as in Table A1 in the paper). We measured the atomic gas fractions as a function of stellar mass for several sample selections, for more details on the sample selection see the paper. For most purposes we recommend you use the mass complete sample selection.

You can use the function below to plot the function we fitted to the mass complete data (parameters for fits to other samples can be found in our paper):

def logfhi(logmstar, gamma0=-0.14, gamma1= -0.854, beta=1.2, M0=8.98,logfhi7=0.45):
    '''The atomic gas sequence of a mass complete sample of galaxies.'''
    return logfhi7 + gamma0*np.log10((10**logmstar)/(10**7)) + (gamma1-gamma0)/beta * np.log10(1+((10**logmstar)/(10**M0))**beta)

Mass-metallicity relation

You can use the function below to plot the function we fitted to the data:

def mzr(logmstar, Z0=8.854, M0=10.49, gamma1=0.2439, beta0=1.20):
    '''The mass-metallicity relation for an emission line flux limited sample'''
    return Z0 - gamma1/beta0 * np.log10(1+(10**logmstar/(10**M0))**-beta0)
