Using Dark Matter Haloes to Learn about Cosmic Acceleration: A New Proposal for a Universal Mass Function
Dark Matter Haloes Cosmic Acceleration

2011/1/11
Structure formation provides a strong test of any cosmic acceleration model because a successful dark energy model must not inhibit {\black or overpredict} the development of observed large-scale stru...

We use two cosmological simulations of structure formation to study the condi-tions under which dark matter haloes emerge from the linear density field. Our analysis focuses on matching sites of halo ...
Linking haloes to galaxies: how many halo properties are needed?

Recent studies emphasize that an empirical relation between the stellar mass of galaxies and
the mass of their host dark matter subhaloes can predict the clustering of galaxies and its
evolution wit...
The rates and modes of gas accretion on to galaxies and their gaseous haloes
galaxies evolution – galaxies formation – intergalactic medium – cos-mology theory

We study the rate at which gas accretes on to galaxies and haloes and investigate whether the accreted gas was shocked to high temperatures before reaching a galaxy.For this purpose we use a suite of ...
Bound and unbound substructures in Galaxy-scale Dark Matter haloes

We analyse the coarse-grained phase-space structure of the six Galaxy-scale dark matter haloes of the Aquarius Project using a state-of-the-art 6D substructure finder. Within r_50, we find that about ...
