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

Paper link: Scholte et al. (2024)

Atomic gas sequence

Measurements of the atomic gas sequence for a mass complete sample of galaxies: Download here.

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

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

Measurements of the mass-metallicity relation for an emission line flux limited sample of galaxies: Download here.

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)
