Alignment of the Milky Way and M31 with their cosmic environment. New insights from constrained Local Group simulations
Hanneke C. Woudenberg, Amina Helmi, Ewoud Wempe +4
The large-scale environment is thought to play an important role in setting galaxy properties. The Milky Way (MW) and Andromeda (M31) reside in the Local Group, embedded in the Loc…
The capture of halo material by orbiting subhaloes
Hang Yang, Simon D. M. White, Liang Gao
When a dark matter halo falls into a more massive object and becomes a subhalo, it typically loses much of its mass through tidal stripping. The reverse process is also possible in…
The mass distribution in and around the Local Group
Ewoud Wempe, Simon D. M. White, Amina Helmi +2
Our Galaxy, Andromeda and their companion dwarf galaxies form the Local Group. Most of the mass in and around it is believed to be dark matter rather than gas or stars, so its dist…
The effect of environment on the mass assembly history of the Milky Way and M31
Ewoud Wempe, Amina Helmi, Simon D. M. White +2
We study the mass growth histories of the halos of Milky Way and M31 analogues formed in constrained cosmological simulations of the Local Group. These simulations constitute a fai…
Constrained cosmological simulations of the Local Group using Bayesian hierarchical field-level inference
Ewoud Wempe, Guilhem Lavaux, Simon D. M. White +3
We present a novel approach based on Bayesian field-level inference capable of resolving individual galaxies within the Local Group (LG), enabling detailed studies of its structure…
