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. High-resolution N-body/SPH simulations in a cosmological context are presented including cold gas and dark matter (DM). A halo with quiet merging activity since redshift z ∼ 3.8 and with a high-spin parameter is analysed that should be an ideal candidate for the formation of an extended galactic disc. We… Expand

Abstract Spiral, fast-rotating galaxies like the Milky Way are the most common type in the Universe. One of the most pressing challenges faced by current models of galaxy formation is the origin ofExpand
Gas Accretion and Angular Momentum
In this chapter, we review the role of gas accretion to the acquisition of angular momentum, both in galaxies and in their gaseous halos. We begin by discussing angular momentum in dark matter halos,Expand
We develop a general physical model for how galactic disks survive and/or are destroyed in mergers and interactions. Based on simple dynamical arguments, we show that gas primarily loses angularExpand
Bulges versus discs: the evolution of angular momentum in cosmological simulations of galaxy formation
We investigate the evolution of angular momentum in simulations of galaxy formation in a cold dark matter universe. We analyse two model galaxies generated in the N-body/hydrodynamic simulations ofExpand
The diverse formation histories of simulated disc galaxies
We analyze the formation histories of 19 galaxies from cosmological smoothed particle hydrodynamics zoom-in resimulations. We construct mock three-colour images and show that the models reproduceExpand
Motivated by a new wave of kinematical tracers in the outer regions of early-type galaxies (ellipticals and lenticulars), we re-examine the role of angular momentum in galaxies of all types. WeExpand

Abstract The gas component plays a major role in the dynamics of spiral galaxies, because of its dissipative character, and its ability to exchange angular momentum with stars in the disk. Due to itsExpand
From discs to bulges: effect of mergers on the morphology of galaxies
We study the effect of mergers on the morphology of galaxies by means of the simulated merger tree approach first proposed by Moster et al. This method combines N-body cosmological simulations andExpand
Angular momentum evolution of bulge stars in disc galaxies in NIHAO
We study the origin of bulge stars and their angular momentum (AM) evolution in 10 spiral galaxies with baryonic masses above 1010M⊙ in the Numerical Investigation of a Hundred Astrophysical ObjectsExpand
Forming disc galaxies in ΛCDM simulations
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 aExpand


Bulgeless galaxies and their angular momentum problem
The specific angular momentum of cold dark matter (CDM) halos in a ΛCDM universe is investigated. Their dimensionless specific angular momentum λ' = j/(VvirRvir) with Vvir and Rvir the virialExpand
Fueling Starburst Galaxies with Gas-rich Mergers
The dynamics of gas are modeled in a merger of two disk/halo galaxies of equal mass using a hybrid N-body/gasdynamics code. Violent tidal forces acting on the disks draw out extended tails andExpand
The angular momentum content of dwarf galaxies: new challenges for the theory of galaxy formation
We compute the specific angular momentum distributions for a sample of low-mass disc galaxies observed by Swaters. We compare these distributions to those of dark matter haloes obtained by Bullock etExpand
Transformations of Galaxies. II. Gasdynamics in Merging Disk Galaxies
In mergers of disk galaxies, gas plays a role quite out of proportion to its relatively modest contribution to the total mass. To study this behavior, we have included gasdynamics in self-consistentExpand
The Assembly of galaxies in a hierarchically clustering universe
We study the formation of galaxies by using $N$-body/hydrodynamics simulations to investigate how baryons collect at the centre of dark matter halos. We treat the dark matter as a collisionless fluidExpand
A merger-driven scenario for cosmological disk galaxy formation
The hierarchical nature of the ?CDM cosmology poses serious difficulties for the formation of disk galaxies. To help resolve these issues, we describe a new, merger-driven scenario for theExpand

Formation of a spiral galaxy in a major merger
We use numerical simulations to examine the structure of merger remnants resulting from collisions of gas-rich spiral galaxies. When the gas fraction of the progenitors is small, the remnantsExpand
