We present a detailed analysis of a disc galaxy forming in a high-resolution fully cosmological simulation to investigate the nature of the outer regions of discs and their relevance for the disc formation process. Specifically, we focus on the phenomenon of misaligned disc components and find that the outer disc warp is a consequence of the misalignment between the inner disc and the surrounding hot gaseous halo. As the infalling cold gas sinks towards the centre of the galaxy, it is strongly… Expand
The creation and persistence of a misaligned gas disc in a simulated early-type galaxy
Massive early-type galaxies (ETGs) commonly have gas discs which are kinematically misaligned with the stellar component. These discs feel a torque from the stars and the angular momentum vectors areExpand
We use cosmological smoothed particle hydrodynamic simulations to study the kinematic signatures of cool gas accretion onto a pair of well-resolved galaxy halos. We find that cold-flow streams andExpand
The halo shape and evolution of polar disc galaxies
We examine the properties and evolution of a simulated polar disc galaxy. This galaxy is composed of two orthogonal discs, one of which contains old stars (old stellar disc) and the other bothExpand
Hierarchical formation of bulgeless galaxies – II. Redistribution of angular momentum via galactic fountains
Within a fully cosmological hydrodynamical simulation, we form a galaxy which rotates at 140 km s −1 , and it is characterized by two loose spiral arms and a bar, indicative of a Hubble-type SBc/dExpand
Interaction between collisionless galactic discs and non-axisymmetric dark matter haloes
Using $N$-body simulations ($N\sim 10^6 - 10^7$), we examine how a non-axisymmetric dark halo affects the dynamical evolution of the structure in collisionless (stellar) discs. We demonstrate how theExpand
Idealized models for galactic disc formation and evolution in ‘realistic’ ΛCDM haloes
We study the dynamics of galactic disk formation and evolution in 'realistic' LambdaCDM haloes with idealized baryonic initial conditions. We add rotating spheres of hot gas at z=1.3 to two fullyExpand
Angular momentum transfer to a Milky Way disc at high redshift
An Adaptive Mesh Refinement cosmological resimulation is analyzed in order to test whether filamentary flows of cold gas are responsible for the build-up of angular momentum within a Milky Way likeExpand
Stellar discs in Aquarius dark matter haloes
We investigate the gravitational interactions between live stellar disks and their dark matter halos, using CDM haloes similar in mass to that of the Milky Way taken from the Aquarius Project. WeExpand
Warps and waves in the stellar discs of the Auriga cosmological simulations
Recent studies have revealed an oscillating asymmetry in the vertical structure of the Milky Way's disc. Here we analyze 16 high-resolution, fully cosmological simulations of the evolution ofExpand
Disc-halo interactions in ΛCDM
We present a new method for embedding a stellar disc in a cosmological dark matter halo and provide a worked example from a {\Lambda}CDM zoom-in simulation. The disc is inserted into the halo at aExpand


Galactic warps induced by cosmic infall
Recent ideas for the origin and persistence of the warps commonly observed in disc galaxies have focused on cosmic infall. We present N-body simulations of an idealized form of cosmic infall on to aExpand
High-redshift clumpy discs and bulges in cosmological simulations
We analyse the first cosmological simulations that recover the fragmentation of high-redshift galactic discs driven by cold streams. The fragmentation is recovered owing to an AMR resolution betterExpand
The role of cold flows in the assembly of galaxy disks
We use high-resolution cosmological hydrodynamical simulations to demonstrate that cold flow gas accretion, particularly along filaments, modifies the standard picture of gas accretion and coolingExpand
How galaxies lose their angular momentum
The processes are investigated by which gas loses its angular momentum during the protogalactic collapse phase, leading to disc galaxies that are too compact with respect to the observations.Expand
The origin of the light distribution in spiral galaxies
We analyse a high-resolution, fully cosmological, hydrodynamical disc galaxy simulation, to study the source of the double-exponential light profiles seen in many stellar discs, and the effects ofExpand
Galactic disc warps due to intergalactic accretion flows onto the disc
The accretion of the intergalactic medium onto the gaseous disc is used to explain the generation of galactic warps. A cup-shaped distortion is expected, due to the transmission of the linearExpand
Star formation in the warped outer pseudoring of the spiral galaxy NGC 3642
NGC 3642 was classied as a spiral galaxy with three rings and no bar. We have performed an HI and optical study of this nearly face-on galaxy. We nd that the nuclear ring might in fact be part of anExpand
Bimodal gas accretion in the Horizon–MareNostrum galaxy formation simulation
The physics of diffuse gas accretion and the properties of the cold and hot modes of accretion on to proto-galaxies between z= 2 and 5.4 is investigated using the large cosmological simulationExpand
We have performed a high mass and force resolution simulation of an idealized galaxy forming from dissipational collapse of gas embedded in a spherical dark matter halo. The simulation includes starExpand
A dark matter disc in three cosmological simulations of Milky Way mass galaxies
Making robust predictions for the phase-space distribution of dark matter at the solar neighbourhood is vital for dark matter direct-detection experiments. To date, almost all such predictions haveExpand
