We compare the properties of galaxies that form in a cosmological simulation without strong feedback to observations of the z = 0 galaxy population. We confirm previous findings that models without strong feedback overproduce the observed galaxy baryonic mass function, especially at the low- and high-mass extremes. Through post-processing we investigate what kinds of feedback would be required to reproduce the statistics of observed galaxy masses and star formation rates. To mimic an extreme…

Galaxies in a simulated ΛCDM Universe – I. Cold mode and hot cores
We study the formation of galaxies in a large volume (50 h −1 Mpc, 2 × 288 3 particles) cosmological simulation, evolved using the entropy and energy-conserving smoothed particle hydrodynamics (SPH)
Stellar Feedback in Galaxies and the Origin of Galaxy-scale Winds
Feedback from massive stars is believed to play a critical role in driving galactic superwinds that enrich the intergalactic medium and shape the galaxy mass function, massmetallicity relation, and
The cosmic baryon cycle and galaxy mass assembly in the FIRE simulations
We use cosmological simulations from the FIRE (Feedback In Realistic Environments) project to study the baryon cycle and galaxy mass assembly for central galaxies in the halo mass range Mhalo ∼
Self-regulated star formation in galaxies via momentum input from massive stars
Feedback from massive stars is believed to play a critical role in shaping the galaxy mass function, the structure of the interstellar medium (ISM) and the low efficiency of star formation, but the
Quenching massive galaxies with on-the-fly feedback in cosmological hydrodynamic simulations
Massive galaxies today typically are not forming stars despite being surrounded by hot gaseous haloes with short central cooling times. This likely owes to some form of ‘quenching feedback’ such as
Galaxies on FIRE (Feedback In Realistic Environments): stellar feedback explains cosmologically inefficient star formation
We present a series of high-resolution cosmological simulations of galaxy formation to z = 0, spanning halo masses ∼10^8–10^(13) M⊙, and stellar masses ∼10^4–10^(11) M⊙. Our simulations include fully
THE ROLE OF STELLAR FEEDBACK IN THE DYNAMICS OF H II REGIONS
Stellar feedback is often cited as the biggest uncertainty in galaxy formation models today. This uncertainty stems from a dearth of observational constraints as well as the great dynamic range
Modeling for Stellar Feedback in Galaxy Formation Simulations
Various heuristic approaches to model unresolved supernova (SN) feedback in galaxy formation simulations exist to reproduce the formation of spiral galaxies and the overall inefficient conversion of
THE HUBBLE SEQUENCE IN GROUPS: THE BIRTH OF THE EARLY-TYPE GALAXIES
The physical mechanisms and timescales that determine the morphological signatures and the quenching of star formation of typical (∼L*) elliptical galaxies are not well understood. To address this
Galaxy evolution in cosmological simulations with outflows ― I. Stellar masses and star formation rates
We examine the growth of the stellar content of galaxies from z = 3 → 0 in cosmological hydrodynamic simulations incorporating parametrized galactic outflows. Without outflows, galaxies overproduce

Breaking the hierarchy of galaxy formation
Recent observations of the distant Universe suggest that much of the stellar mass of bright galaxies was already in place at z > 1. This presents a challenge for models of galaxy formation because
