The Magellanic Group and the Seven Dwarfs
Elena D'Onghia, George Lake
The Magellanic Clouds were the largest members of a group of dwarf galaxies that entered the Milky Way (MW) halo at late times. This group, dominated by the LMC, contained ~4% of t…
Merger and Ring Galaxy Formation Rates at z<=2
E. D'Onghia, M. Mapelli, B. Moore
We compare the observed merger rate of galaxies over cosmic time and the frequency of collisional ring galaxies (CRGs), with analytic models and halo merger and collision rates fro…
Breaking up the Magellanic Group into the Milky Way Halo: Understanding the Local Dwarf Galaxy Properties
Elena D'Onghia
We use a numerical simulation of a loose group containing a Milky Way halo to probe that in the hierarchical universe the Magellanic Clouds and some dSphs have been accreted into t…
Small Dwarf Galaxies Within Larger Dwarfs: Why Some Are Luminous While Most Go Dark
Elena D'Onghia, George Lake
We consider the possibility that the Magellanic Clouds were the largest members of a group of dwarf galaxies that entered the Milky Way (MW) halo at late times. Seven of the eleven…
The Fossil Phase in the Life of a Galaxy Group
Alexander M. von Benda-Beckmann, Elena D'Onghia, Stefan Gottloeber +4
We investigate the origin and evolution of fossil groups in a concordance LCDM cosmological simulation. We consider haloes with masses between $(1-5)\times10^{13} \hMsun$ and study…
Universal Substructure Distributions in LCDM halos: Can we find a Fossil Group?
E. D'Onghia, A. V. Maccio', G. Lake +2
We use large cosmological N-body simulations to study the subhalo population in galaxy group sized halos. In particular, we look for fossil group candidates with typical masses ~10…
