Understanding the shape of the halo-mass and galaxy-mass cross-correlation functions
E. Hayashi, S. D. M. White
We use the Millennium Simulation to measure the cross-correlation between halo centres and mass (or equivalently the average density profiles of dark haloes) in a LCDM cosmology. W…
The Shape of the Gravitational Potential in Cold Dark Matter Halos
E. Hayashi, J. F. Navarro, V. Springel
We use a set of cosmological N-body simulations to investigate the structural shape of galaxy-sized cold dark matter (CDM) halos. Unlike most previous work on the subject - which d…
Hiding Cusps in Cores: Kinematics of Disk Galaxies in Triaxial Dark Matter Halos
Eric Hayashi, Julio F. Navarro
We study the kinematics of gaseous disks in triaxial dark matter halos using the closed-loop orbit solutions in non-axisymmetric potentials. The orbits are in general non-circular…
How Rare is the Bullet Cluster?
Eric Hayashi, Simon D. M. White
The galaxy cluster 1E 0657-56 has a bullet-like subcluster that is moving away from the centre of the main cluster at high speed. Markevitch et al. (2004) recently estimated a rela…
Disk Galaxy Rotation Curves in Triaxial CDM Halos
E. Hayashi, J. F. Navarro, A. Jenkins +7
We use N-body hydrodynamical simulations to study the structure of disks in triaxial potentials resembling CDM halos. Our analysis focuses on the accuracy of the dark mass distribu…
The Inner Structure of LambdaCDM Halos III: Universality and Asymptotic Slopes
Julio F. Navarro, Eric Hayashi, Chris Power +6
We investigate the mass profile of LambdaCDM halos using a suite of numerical simulations spanning five decades in halo mass, from dwarf galaxies to rich galaxy clusters. Our analy…
