The survival and disruption of CDM micro-haloes: implications for direct and indirect detection experiments
Tobias Goerdt, Oleg Y. Gnedin, Ben Moore +2
If the dark matter particle is a neutralino then the first structures to form are cuspy cold dark matter (CDM) haloes collapsing after redshifts z ~ 100 in the mass range 10^{-6} -…
Dark Satellites and Cosmic Reionization
Andrea V. Maccio', Ben Moore, Joachim Stadel +1
A possible explanation of the present discrepancy between the abundance of galactic subhaloes predicted by N-Body simulations with those observed in the Local Group is presented. W…
Properties of Galaxy Groups in the SDSS: II.- AGN Feedback and Star Formation Truncation
Simone M. Weinmann, Frank C. van den Bosch, Xiaohu Yang +3
Successfully reproducing the galaxy luminosity function and the bimodality in the galaxy distribution requires a mechanism that can truncate star formation in massive haloes. Curre…
Dynamical friction in constant density cores: a failure of the Chandrasekhar formula
J. I. Read, Tobias Goerdt, Ben Moore +3
Using analytic calculations and N-body simulations we show that in constant density (harmonic) cores, sinking satellites undergo an initial phase of very rapid (super-Chandrasekhar…
An optimum time-stepping scheme for N-body simulations
Marcel Zemp, Joachim Stadel, Ben Moore +1
We present a new time-stepping criterion for N-body simulations that is based on the true dynamical time of a particle. This allows us to follow the orbits of particles correctly i…
An alternative to grids and glasses: Quaquaversal pre-initial conditions for N-body simulations
Steen H. Hansen, Oscar Agertz, Michael Joyce +3
N-body simulations sample their initial conditions on an initial particle distribution, which for cosmological simulations is usually a glass or grid, whilst a Poisson distribution…
