What causes the formation of discs and end of bursty star formation?

PF Hopkins, AB Gurvich, X Shen… - Monthly Notices of …, 2023 - academic.oup.com
As they grow, galaxies can transition from irregular/spheroidal with 'bursty'star formation
histories (SFHs), to discy with smooth SFHs. But even in simulations, the direct physical …
