We used fully cosmological, high-resolution N-body + smooth particle hydrodynamic (SPH) simulations to follow the formation of disc galaxies with rotational velocities between 135 and 270km s -1 in a A cold dark matter (CDM) universe. The simulations include gas cooling, star formation, the effects of a uniform ultraviolet (UV) background and a physically motivated description of feedback from supernovae (SNe). The host dark matter haloes have a spin and last major merger redshift typical of… 
The formation of disc galaxies in high-resolution moving-mesh cosmological simulations
We present cosmological hydrodynamical simulations of eight Milky Way-sized haloes that have been previously studied with dark matter only in the Aquarius project. For the first time, we employ the
Baryonic and dark matter distribution in cosmological simulations of spiral galaxies
We study three cosmological hydrodynamical simulations of Milky Way(MW)-sized haloes including a comparison with the dark matter(DM)-only counterparts. We find one of our simulated galaxies with
The formation and survival of discs in a ΛcDM universe
We study the formation of galaxies in acold dark matter (� CDM) universe using high- resolution hydrodynamical simulations with a multiphase treatment of gas, cooling and feed- back, focusing on the
FORMING EARLY-TYPE GALAXIES IN ΛCDM SIMULATIONS. I. ASSEMBLY HISTORIES
We present a sample of nine high-resolution cosmological simulations in the mass range of M vir = 7 × 1011-4 × 1012 M ☉ starting from ΛCDM initial conditions. Our simulations include primordial
Bulgeless dwarf galaxies and dark matter cores from supernova-driven outflows
TLDR
Hydrodynamical simulations in a framework assuming the presence of CDM and a cosmological constant are reported in which the inhomogeneous interstellar medium is resolved and the analogues of dwarf galaxies—bulgeless and with shallow central dark-matter profiles—arise naturally in these simulations.
The formation of disc galaxies in a ΛCDM universe
We study the formation of disc galaxies in a fully cosmological framework using adaptive mesh refinement simulations. We perform an extensive parameter study of the main subgrid processes that
Formation and evolution of dwarf galaxies in the CDM Universe
We first review the results of the tidal stirring model for the transformation of gas-rich dwarf irregulars into dwarf spheroidals, which turns rotationally supported stellar systems into pressure
The structure of the interstellar medium of star‐forming galaxies
We develop and implement numerical methods for including stellar feedback in galaxy-scale numerical simulations. Our models include simplified treatments of heating by Type I and Type II supernovae,
BARYONS MATTER: WHY LUMINOUS SATELLITE GALAXIES HAVE REDUCED CENTRAL MASSES
Using high-resolution cosmological hydrodynamical simulations of Milky Way-massed disk galaxies, we demonstrate that supernovae feedback and tidal stripping lower the central masses of bright (–15 <
REPRODUCING THE STELLAR MASS/HALO MASS RELATION IN SIMULATED ΛCDM GALAXIES: THEORY VERSUS OBSERVATIONAL ESTIMATES
We examine the present-day total stellar-to-halo mass (SHM) ratio as a function of halo mass for a new sample of simulated field galaxies using fully cosmological, ?CDM, high-resolution SPH + N-body

In the generic CDM cosmogony, dark-matter haloes emerge too lumpy and centrally concentrated to host observed galactic discs. Moreover, discs are predicted to be smaller than those observed. We argue
