The large-scale structure of the halo of the Andromeda galaxy II. Hierarchical structure in the Pan-Andromeda Archaeological Survey
Alan W. McConnachie, Rodrigo Ibata, Nicolas Martin +29
The Pan-Andromeda Archaeological Survey is a survey of square degrees centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive pano…
We are not the 99 percent: quantifying asphericity in the distribution of Local Group satellites
Jaime E. Forero-Romero, Veronica Arias
We use simulations to build an analytic probability distribution for the asphericity in the satellite distribution around Local Group (LG) type galaxies in the Lambda Cold Dark Mat…
Stability of Satellite Planes in M31 II: Effects of the Dark Subhalo Population
Nuwanthika Fernando, Veronica Arias, Geraint F. Lewis +2
The planar arrangement of nearly half the satellite galaxies of M31 has been a source of mystery and speculation since it was discovered. With a growing number of other host galaxi…
On the Stability of Satellite Planes I: Effects of Mass, Velocity, Halo Shape and Alignment
Nuwanthika Fernando, Veronica Arias, Magda Guglielmo +3
The recently discovered vast thin plane of dwarf satellites orbiting the Andromeda Galaxy (M31) adds to the mystery of the small scale distribution of the Local Group's galaxy popu…
NGC 147, NGC 185 and CassII: a genetic approach to orbital properties, star formation and tidal debris
Veronica Arias, Magda Guglielmo, Nuwanthika Fernando +9
NGC147, NGC185 and CassiopeiaII (CassII) have similar positions in the sky, distances and measured line of sight velocities. This proximity in phase space suggests that these three…
A thousand shadows of Andromeda: rotating planes of satellites in the Millennium-II cosmological simulation
Rodrigo A. Ibata, Neil G. Ibata, Geraint F. Lewis +5
In a recent contribution, Bahl \& Baumgardt investigated the incidence of planar alignments of satellite galaxies in the Millennium-II simulation, and concluded that vast thin plan…
