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…
On the persistence of two small-scale problems in ΛCDM
Marcel S. Pawlowski, Benoit Famaey, David Merritt +1
We investigate the degree to which the inclusion of baryonic physics can overcome two long-standing problems of the standard cosmological model on galaxy scales: (i) the problem of…
Masses of the components of SB2 binaries observed with Gaia. II. Masses derived from PIONIER interferometric observations for Gaia validation
J. -L. Halbwachs, H. M. J. Boffin, J. -B. Le Bouquin +15
In anticipation of the Gaia astrometric mission, a sample of spectroscopic binaries is being observed since 2010 with the Sophie spectrograph at the Haute--Provence Observatory. Ou…
Dynamical measurement of the stellar surface density of face-on galaxies
Garry W. Angus, Gianfranco Gentile, Benoit Famaey
The DiskMass survey recently provided measurements of the vertical velocity dispersions of disk stars in a sample of nearly face-on galaxies. By setting the disk scale-heights to b…
Combined Solar System and rotation curve constraints on MOND
A. Hees, B. Famaey, G. W. Angus +1
The Modified Newtonian Dynamics (MOND) paradigm generically predicts that the external gravitational field in which a system is embedded can produce effects on its internal dynamic…
Quasi integral of motion for axisymmetric potentials
O. Bienaymé, A. C. Robin, B. Famaey
We present an estimate of the third integral of motion for axisymmetric three-dimensional potentials. This estimate is based on a Staeckel approximation and is explicitly written a…
