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 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…
Preparing for Rubin-LSST -- Detecting Brightest Cluster Galaxies with Machine Learning in the LSST DP0.2 simulation
Aline Chu, Ludvig Doeser, Simon Ding +1
The future Rubin Legacy Survey of Space and Time (LSST) is expected to deliver its first data release in the current of 2025. The upcoming survey will provide us with images of gal…
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…
Distinct distributions of elliptical and disk galaxies across the Local Supercluster as a CDM prediction
Till Sawala, Carlos Frenk, Jens Jasche +2
Galaxies of different types are not equally distributed in the Local Universe. In particular, the supergalactic plane is prominent among the brightest ellipticals, but inconspicuou…
