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…

Modelling of long gamma-ray burst host galaxies at cosmic noon from damped Lyman-α absorption statistics

J. -K. Krogager, A. De Cia, K. E. Heintz +11

We study the properties of long gamma-ray burst (GRB) host galaxies using a statistical modelling framework derived to model damped Lyman- absorbers (DLAs) in quasar spectra at…
