Stellar population synthesis models with a physically varying IMF
A new stellar population synthesis code shows that assuming a galaxy-wide IMF that varies with star formation rate and metallicity changes predicted mass-to-light ratios, colors, luminosities, and remnant fractions of galaxies compared to an invariant canonical IMF.
