Dark matter in the Milky Way: Measurements up to 3 kpc from the Galactic plane above the Sun
O. Bienaymé, A. C. Robin, J. -B. Salomon +1
We probe the gravitational force perpendicular to the Galactic plane at the position of the Sun based on a sample of red giants, with measurements taken from the DR3 Gaia catalogue…
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 LMC impact on the kinematics of the Milky Way satellites: clues from the running solar apex
Dmitry Makarov, Sergey Khoperskov, Danila Makarov +3
Dwarf galaxies provide a unique opportunity for studying the evolution of the Milky Way (MW) and the Local Group as a whole. Analysing the running solar apex based on the kinematic…
A self-consistent dynamical model of the Milky Way disc adjusted to Gaia data
A. C. Robin, O. Bienaymé, J. B. Salomon +6
This paper shows how a self-consistent dynamical model can be obtained by fitting the gravitational potential of the Milky Way to the stellar kinematics and densities from Gaia dat…
Deciphering the evolution of the Milky Way discs: Gaia APOGEE Kepler giant stars and the Besançon Galaxy Model
N. Lagarde, C. Reylé, C. Chiappini +13
We investigate the properties of the double sequences of the Milky Way discs visible in the [/Fe] vs [Fe/H] diagram. In the framework of Galactic formation and evolution, we dis…
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…
Kinematics and dynamics of Gaia red clump stars
Jean-Baptiste Salomon, Olivier Bienaymé, Céline Reylé +2
We analyse the kinematics and dynamics of a homogeneous sample of red clump stars selected from the second Gaia data release catalogue in the direction of the Galactic poles. The l…
Tidally induced morphology of M33 in hydrodynamical simulations of its recent interaction with M31
Marcin Semczuk, Ewa L. Lokas, Jean-Baptiste Salomon +2
We present a hydrodynamical model of M33 and its recent interaction with M31. This scenario was previously proposed in the literature in order to explain the distorted gaseous and…
Masses of the components of SB2 binaries observed with Gaia. III. Accurate SB2 orbits for 10 binaries and masses of HIP 87895
Flavien Kiefer, Jean-Louis Halbwachs, Frédéric Arenou +9
In anticipation of the Gaia astrometric mission, a large sample of spectroscopic binaries has been observed since 2010 with the SOPHIE spectrograph at the Haute--Provence Observato…
The Transverse velocity of the Andromeda system, derived from the M31 satellite population
J. -B. Salomon, R. A. Ibata, B. Famaey +2
We present a dynamical measurement of the tangential motion of the Andromeda system, the ensemble consisting of the Andromeda Galaxy (M31) and its satellites. The system is modelle…
The intrinsic ellipticity of dwarf spheroidal galaxies: constraints from the Andromeda system
Jean-Baptiste Salomon, Rodrigo Ibata, Nicolas Martin +1
We present a study of the intrinsic deprojected ellipticity distribution of the satellite dwarf galaxies of the Andromeda galaxy, assuming that their visible components have a prol…
