Variation of the stellar initial mass function in semi-analytical models. III. Testing the cosmic-ray regulated integrated galaxy-wide initial mass function
Context. In our previous work, we derived the CR-IGIMF, which is a new scenario for a variable stellar initial mass function (IMF) that combines numerical results on the role played by cosmic rays (CR) in setting the thermal state of star-forming gas with the analytical approach of the integrated galaxy-wide IMF (IGIMF). Aims: In this work, we
