Pressure-regulated feedback-modulated star formation as a subgrid model for galaxy formation simulations
Sarah M. R. Jeffreson, Eve C. Ostriker, Chang-Goo Kim +1
We present a new subgrid model for interstellar gas evolution in cosmological simulations of galaxy formation, based on the pressure-regulated, feedback-modulated (PRFM) theory of…
Unmasking Stellar Feedback-Driven Bubbles: Identification and Properties Analysis
Aaron Angress, Michael M. Foley, Sarah M. R. Jeffreson +2
The identification and tracking of stellar feedback-driven galaxy bubbles is an important topic in star formation and galactic structure research. However, current observational an…
What Suppresses Star Formation in Bulge-Dominated Early-Type Galaxies?
Lori E. Porter, S. M. R. Jeffreson, Greg L. Bryan +1
We investigate the physical origin of star formation suppression in gas-rich early-type galaxies using five high-resolution hydrodynamical idealized galaxy simulations, performed w…
Applying a star formation model calibrated on high-resolution interstellar medium simulations to cosmological simulations of galaxy formation
Jan D. Burger, Volker Springel, Eve C. Ostriker +11
Modern high-resolution simulations of the interstellar medium (ISM) have shown that key factors in governing star formation are the competing influences of radiative dissipation, p…
