On the relation between radial alignment of dark matter subhalos and host mass in cosmological simulations
Astrophysical Institute Potsdam, An der Sternwarte 16, Germany
We explore the dependence of the radial alignment of subhalos on the mass of the host halo they orbit in. We have 25 well resolved host dark matter halos at our disposal ranging from 1015 h-1 M๏ down to 1012 h-1 M๏. We note that the radial alignment is independent of host halo mass and the distribution of cosθ is well fitted by a simple power law P(cosθ) ∝ cos4θ.
