On the formation of dwarf galaxies and stellar halos
J. I. Read, A. P. Pontzen, M. Viel
Using analytic arguments and a suite of very high resolution (10^3 Msun per particle) cosmological hydro-dynamical simulations, we argue that high redshift, z ~ 10, M ~ 10^8 Msun h…
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…
The importance of tides for the Local Group dwarf spheroidals
J. I. Read, M. I. Wilkinson, N. Wyn Evans +2
There are two main tidal effects which can act on the Local Group dwarf spheroidals (dSphs): tidal stripping and tidal shocking. Using N-body simulations, we show that tidal stripp…
The tidal stripping of satellites
J. I. Read, M. I. Wilkinson, N. W. Evans +2
We present an improved analytic calculation for the tidal radius of satellites and test our results against N-body simulations. The tidal radius in general depends upon four factor…
Tidal streams in a MOND potential: constraints from Sagittarius
J. I. Read, Ben Moore
We compare orbits in a thin axisymmetric disc potential in MOND to those in a thin disc plus near-spherical dark matter halo predicted by a CDM cosmology. Remarkably, the amount…
