Variable gravitational potential of Milky Way analogues in HESTIA suite
Naira R. Arakelyan, Sergey V. Pilipenko, Stefan Gottlöber +3
Investigations of trajectories of various objects orbiting the Milky Way (MW) halo with modern precision, achievable in observations by Gaia, requires sophisticated, non-stationary…
Exploring the centre of mass properties of LG-like galaxies
Jean-Baptiste Salomon, Noam Libeskind, Yehuda Hoffman
From high resolution cosmological simulations of the Local Group in realistic environment, namely HESTIA simulations, we study the position and kinematic deviations that may arise…
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 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 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…
On the Mass Assembly History of the Local Group
Edoardo Carlesi, Yehuda Hoffman, Stefan Gottlöber +4
In this work an ensemble of simulated Local Group analogues is used to constrain the properties of the mass assembly history of the Milky Way (MW) and Andromeda (M31) galaxies. The…
