The proper motion of Andromeda from Gaia eDR3: confirming a nearly radial orbit
J. -B. Salomon, R. Ibata, C. Reylé +4
We present an analysis of the proper motion of the Andromeda galaxy (M31), based on the Early Third Data Release of the Gaia mission. We use the Gaia photometry to select young blu…
The coherent motion of Cen A dwarf satellite galaxies remains a challenge for CDM cosmology
Oliver Müller, Marcel S. Pawlowski, Federico Lelli +6
The plane-of-satellites problem is one of the most severe small-scale challenges for the standard CDM cosmological model: several dwarf galaxies around the Milky Way and Androme…
Associations of dwarf galaxies in a CDM Universe
C. Y. Yaryura, M. G. Abadi, S. Gottlober +6
Associations of dwarf galaxies are loose systems composed exclusively of dwarf galaxies. These systems were identified in the Local Volume for the first time more than thirty years…
The sum of the masses of the Milky Way and M31: a likelihood-free inference approach
Pablo Lemos, Niall Jeffrey, Lorne Whiteway +3
We use Density Estimation Likelihood-Free Inference, Cold Dark Matter simulations of galaxy pairs, and data from Gaia and the Hubble Space Telescope to infer the sum…
The Halo Spin Transition as a Probe of Dark Energy
Jounghun Lee, Noam I Libeskind
We present a numerical evidence supporting the claim that the mass-dependent transitions of the halo spin orientations from the intermediate to the minor principal directions of th…
The Hestia project: simulations of the Local Group
Noam I. Libeskind, Edoardo Carlesi, Rob J. J. Grand +19
We present the Hestia simulation suite: High-resolutions Environmental Simulations of The Immediate Area, a set of cosmological simulations of the Local Group. Initial conditions c…
