Sussing Merger Trees : The Impact of Halo Merger Trees on Galaxy Properties in a Semi-Analytic Model
Jaehyun Lee, Sukyoung K. Yi, Pascal J. Elahi +13
A halo merger tree forms the essential backbone of a semi-analytic model for galaxy formation and evolution. Recent studies have pointed out that extracting merger trees from numer…
Accretion in action: phase space coherence of stellar debris and globular clusters in Andromeda's South-West Cloud
Dougal Mackey, Geraint Lewis, Michelle Collins +13
A central tenet of the current cosmological paradigm is that galaxies grow over time through the accretion of smaller systems. Here, we present new kinematic measurements near the…
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…
