Solving the puzzle of subhalo spins
Yang Wang, Weipeng Lin, Frazer R. Pearce +3
Investigating the spin parameter distribution of subhaloes in two high resolution isolated halo simulations, re- cent work by Onions et al. suggested that typical subhalo spins are…
Kinematics and simulations of the stellar stream in the halo of the Umbrella Galaxy
Caroline Foster, Hanni Lux, Aaron J. Romanowsky +9
We study the dynamics of faint stellar substructures around the Umbrella Galaxy, NGC 4651, which hosts a dramatic system of streams and shells formed through the tidal disruption o…
Kinematic transitions and streams in galaxy halos
A. J. Romanowsky, J. A. Arnold, J. P. Brodie +7
The chemo-dynamics of galaxy halos beyond the Local Group may now be mapped out through the use of globular clusters and planetary nebulae as bright tracer objects, along with deep…
Constraining the Milky Way Halo Shape Using Thin Streams
H. Lux, J. I. Read, G. Lake +1
Tidal streams are a powerful probe of the Milky Way (MW) potential shape. In this paper, we introduce a simple test particle method to fit stream data, using a Markov Chain Monte C…
NGC 5466: a unique probe of the Galactic halo shape
H. Lux, J. I. Read, G. Lake +1
Stellar streams provide unique probes of galactic potentials, with the longer streams normally providing the cleaner measurements. In this paper, we show an example of a short tida…
Determining orbits for the Milky Way's dwarfs
H. Lux, J. I. Read, G. Lake
We calculate orbits for the Milky Way dwarf galaxies with proper motions, and compare these to subhalo orbits in a high resolution cosmological simulation. We use the simulation da…

We calculate orbits for the Milky Way dwarf galaxies with proper motions, and compare these to subhalo orbits in a high resolution cosmological simulation. We use this same simulat…
