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 …

Pressure-regulated, feedback-modulated star formation in disk galaxies

EC Ostriker, CG Kim - The Astrophysical Journal, 2022‏ - iopscience.iop.org
The star formation rate (SFR) in galactic disks depends on both the quantity of the available
interstellar medium (ISM) gas and its physical state. Conversely, the ISM's physical state …
