The bimodality in observed present-day galaxy colours has long been a challenge for hierarchical galaxy formation models, as it requires some physical process to quench (and keep quenched) star formation in massive galaxies. Here we examine phenomenological models of quenching by post-processing the star formation histories of galaxies from cosmological hydrodynamic simulations that reproduce observations of star-forming galaxies reasonably well. We consider recipes for quenching based on major… 
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
Star Formation Quenching Timescale of Central Galaxies in a Hierarchical Universe
Central galaxies make up the majority of the galaxy population, including the majority of the quiescent population at . Thus, the mechanism(s) responsible for quenching central galaxies play a
The growth of red sequence galaxies in a cosmological hydrodynamic simulation
We examine the cosmic growth of the red sequence in a cosmological hydrodynamic simulation that includes a heuristic prescription for quenching star formation that yields a realistic passive galaxy
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
mufasa: the assembly of the red sequence
We examine the growth and evolution of quenched galaxies in the Mufasa cosmological hydrodynamic simulations that include an evolving halo mass-based quenching prescription, with galaxy colours
Smoothly rising star formation histories during the reionization epoch
Cosmological hydrodynamic simulations robustly predict that high-redshift galaxy star formation histories (SFHs) are smoothly rising and vary with mass only by a scalefactor. We use our latest
On the role of supermassive black holes in quenching star formation in local central galaxies
We analyse the role of AGN feedback in quenching star formation for massive, central galaxies in the local Universe. In particular, we compare the prediction of two semi-analytic models (l-galaxies
Hot gas in massive haloes drives both mass quenching and environment quenching
Observations indicate that galaxies with high stellar masses or in dense environments have low specific star formation rates, i.e. they are quenched. Based on cosmological hydrodynamic simulations
The environmental dependence of rapidly quenching and rejuvenating galaxies
By combining H α flux measurements from the Sloan Digital Sky Survey (SDSS) with ultraviolet (UV) flux observations from the Galaxy Evolution Explorer (GALEX), we examine the environmental
Sub one per cent mass fractions of young stars in red massive galaxies
Early-type galaxies are considered to be the end products of massive galaxy formation 1 . Optical spectroscopic studies reveal that massive early-type galaxies formed the bulk of their stars over


Galaxy bimodality due to cold flows and shock heating
We address the origin of the robust bimodality observed in galaxy properties about a characteristic stellar mass ∼3 x 10 10 M ⊙ . Less massive galaxies tend to be ungrouped blue star forming discs,
Black Holes in Galaxy Mergers: The Formation of Red Elliptical Galaxies
We use hydrodynamical simulations to study the color transformations induced by star formation and active galactic nuclei (AGNs) during major mergers of spiral galaxies. Our modeling accounts for
The Physical and Photometric Properties of High-Redshift Galaxies in Cosmological Hydrodynamic Simulations
We study the physical and photometric properties of galaxies at z = 4 in cosmological hydrodynamic simulations of a ΛCDM universe. We focus on galaxies satisfying the ``B dropout" criteria of the
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
The correlation of star formation quenching with internal galaxy properties and environment
We investigate the correlation of star formation quenching with internal galaxy properties and large-scale environment (halo mass) in empirical data and theoretical models. We make use of the

We reproduce the blue and red sequences in the observed joint distribution of colour and magnitude for galaxies at low and high redshifts using hybrid N-body/semi-analytic simulations of galaxy

We examine the origin of clustercentric gradients in the star formation rates and colors of rich cluster galaxies within the context of a simple model where clusters are built through the ongoing

We explore galaxy properties and their link with environment and clustering using a population of ∼1000 galaxies formed in a high-resolution hydrodynamic simulation of the A cold dark matter
A semi-analytic model for the co-evolution of galaxies, black holes and active galactic nuclei
We present a new semi-analytic model that self-consistently traces the growth of supermassive black holes (BH) and their host galaxies within the context of the Lambda cold dark matter (� CDM)
The growth of supermassive black holes and their host galaxies are thought to be linked, but the precise nature of this symbiotic relationship is still poorly understood. Both observations and
