Using high resolution N-body simulations of stellar disks embedded in cosmologically motivated dark matter halos, we study the evolution of bars and the transfer of angular momentum between halos and bars. We find that dynamical friction results in some transfer of angular momentum to the halo, but the effect is much smaller than previously found in low resolution simulations and is incompatible with early analytical estimates. After 5 Gyrs of evolution the stellar component loses only 5% – 7… 
The Effect of Bulge Mass on Bar Pattern Speed in Disk Galaxies
We present a study of the effect of bulge mass on the evolution of bar pattern speed in isolated disk galaxies using N-body simulations. Earlier studies have shown that disk stars at the inner
Dynamics of barred galaxies: effects of disc height
We study dynamics of bars in models of disc galaxies embedded in realistic dark matter haloes. We find that disc thickness plays an important, if not dominant, role in the evolution and structure of
Spinning dark matter haloes promote bar formation
Stellar bars are the most common non-axisymmetric structures in galaxies and their impact on the evolution of disc galaxies at all cosmological times can be significant. Classical theory predicts
We examine the bar instability in galactic models with an exponential disk and a cuspy dark matter (DM) halo with a Navarro-Frenk-White cosmological density profile. The equilibrium models are
The formation and evolution of bars in low surface brightness galaxies with cold dark matter haloes
We perform several high-resolution simulations of low surface brightness galaxies (LSBGs) embedded in cold dark matter haloes to study how likely bar formation is in such systems. The behaviour of
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 a
Revisiting the tension between fast bars and the ΛCDM paradigm
The pattern speed with which galactic bars rotate is intimately linked to the amount of dark matter in the inner regions of their host galaxies. In particular, dark matter haloes act to slow down
The Impact of Galactic Winds on the Angular Momentum of Disk Galaxies in the Illustris Simulation
Observed galactic disks have specific angular momenta similar to expectations for typical dark matter halos in $\Lambda$CDM. Cosmological hydrodynamical simulations have recently reproduced this
The Formation of a Realistic Disk Galaxy in Λ-dominated Cosmologies
We simulate the formation of a realistic disk galaxy within the hierarchical scenario of structure formation and study its internal properties to the present epoch. We use a set of smoothed particle
The bar–halo interaction – II. Secular evolution and the religion of N-body simulations
This paper explores resonance-driven secular evolution between a bar and dark matter halo using N-body simulations. We make direct comparisons to our analytic theory to demonstrate the great


We use fully self-consistent N-body simulations of barred galaxies to show that dynamical friction from a dense dark matter halo dramatically slows the rotation rate of bars. Our result supports
Dark Halos: The Flattening of the Density Cusp by Dynamical Friction
N-body simulations and analytical calculations of the gravitational collapse in an expanding universe predict that halos should form with a diverging inner density profile, the cusp. There are some
Constraints from Dynamical Friction on the Dark Matter Content of Barred Galaxies
We show that bars in galaxy models having halos of moderate density and a variety of velocity distributions all experience a strong drag from dynamical friction unless the halo has large angular
Measurement of fast bars in a sample of early‐type barred galaxies
We present surface photometry and stellar kinematics of a sample of five SB0 galaxies: ESO 139-G009, IC 874, NGC 1308, NGC 1440 and NGC 3412. We measured their bar pattern speed using the
Bar-driven Dark Halo Evolution: A Resolution of the Cusp-Core Controversy
Simulations predict that the dark matter halos of galaxies should have central cusps, while those inferred from observed galaxies do not have cusps. We demonstrate, using both linear perturbation
Cuspy dark matter haloes and the Galaxy
The microlensing optical depth to Baade's Window constrains the minimum total mass in baryonic matter within the Solar circle to be greater than ∼, assuming the inner Galaxy is barred with viewing
Velocity dispersions of dwarf spheroidal galaxies: dark matter versus MOND
We present predictions for the line-of-sight velocity dispersion profiles of dwarf spheroidal galaxies and compare them to observations in the case of the Fornax dwarf. The predictions are made in
A dynamical instability of bars in disk galaxies
STRONG, rapidly rotating, persistent bars readily form in numerical simulations of initially axisymmetric disk galaxies1–4. The global dynamical instability responsible for this behaviour is a great
Dark Matter Substructure within Galactic Halos
We use numerical simulations to examine the substructure within galactic and cluster mass halos that form within a hierarchical universe. Clusters are easily reproduced with a steep mass spectrum of
Velocity Bias in a Λ Cold Dark Matter Model
We use a high-resolution N-body simulation to study the velocity bias of dark matter halos, the difference in the velocity fields of dark matter and halos, in a flat low-density cold dark matter
