Cosmic vorticity and the origin of halo spins
Noam I Libeskind, Yehuda Hoffman, Matthias Steinmetz +3
In the standard model of cosmology, structure emerges out of non-rotational flow and the angular momentum of collapsing halos is induced by tidal torques. The growth of halo angula…
Subhaloes gone Notts: Spin across subhaloes and finders
Julian Onions, Yago Ascasibar, Peter Behroozi +15
We present a study of a comparison of spin distributions of subhaloes found associated with a host halo. The subhaloes are found within two cosmological simulation families of Milk…
The halo mass function through the cosmic ages
William A. Watson, Ilian T. Iliev, Anson D'Aloisio +3
In this paper we investigate how the halo mass function evolves with redshift, based on a suite of very large (with N_p = 3072^3 - 6000^3 particles) cosmological N-body simulations…
The velocity shear tensor: tracer of halo alignment
Noam I. Libeskind, Yehuda Hoffman, Jaime Forero-Romero +4
The alignment of DM halos and the surrounding large scale structure (LSS) is examined in the context of the cosmic web. Halo spin, shape and the orbital angular momentum of subhalo…
Galaxies going MAD: The Galaxy-Finder Comparison Project
Alexander Knebe, Noam I. Libeskind, Frazer Pearce +8
With the ever increasing size and complexity of fully self-consistent simulations of galaxy formation within the framework of the cosmic web, the demands upon object finders for th…
N-body simulations with a cosmic vector for dark energy
Edoardo Carlesi, Alexander Knebe, Gustavo Yepes +3
We present the results of a series of cosmological -body simulations of a Vector Dark Energy (VDE) model, performed using a suitably modified version of the publicly available \…
