Variation of the stellar initial mass function in semi-analytical models III: testing the cosmic ray regulated integrated galaxy-wide initial mass function
Fabio Fontanot, Francesco La Barbera, Gabriella De Lucia +6
In our previous work, we derive the CR-IGIMF: a new scenario for a variable stellar initial mass function (IMF), which combines numerical results on the role played by cosmic rays…

Quiescent galaxies at : observations vs. models
Rachele Cecchi, Micol Bolzonella, Andrea Cimatti +1
The presence of massive quiescent galaxies at high redshifts is still a challenge for most models of galaxy formation. The aim of this work is to compare the observed number densit…
