A correlation between spin parameter and dark matter halo mass
Alexander Knebe, Chris Power
Using a set of high-resolution dark matter only cosmological simulations we found a correlation between the dark matter halo mass M and its spin parameter lambda for objects formin…
Dynamics of substructures in warm dark-matter cosmologies
Bastian Arnold, Alexander Knebe, Chris Power +1
We performed cosmological simulations based upon both a cold dark matter (CDM) and a warm dark matter (WDM) model. The focus of our investigations lies with selected spatial and ki…
On the relation between radial alignment of dark matter subhalos and host mass in cosmological simulations
Alexander Knebe, Nadya Draganova, Chris Power +4
We explore the dependence of the radial alignment of subhalos on the mass of the host halo they orbit in. As the effect is seen on a broad range of scales including massive cluster…
The Dynamics of Subhalos in Warm Dark Matter Models
Alexander Knebe, Bastian Arnold, Chris Power +1
We present a comparison of the properties of substructure halos (subhalos) orbiting within host halos that form in Cold Dark Matter (CDM) and Warm Dark Matter (WDM) cosmologies. Ou…
On the Correlation between Spin Parameter and Halo Mass
Alexander Knebe, Chris Power
We report on a correlation between virial mass M and spin parameter lambda for dark matter halos forming at redshifts z > 10. We find that the spin parameter decreases with increas…
The Tidal Streams of Disrupting Subhaloes in Cosmological Dark Matter Haloes
Kristin Warnick, Alexander Knebe, Chris Power
(abridged) We present a detailed analysis of the properties of tidally stripped material from disrupting substructure haloes or subhaloes in a sample of high resolution cosmologica…
