Antaeus: a retrograde group of tidal debris in the Milky Way's disk plane
Pierre-Antoine Oria, Wassim Tenachi, Rodrigo Ibata +5
We present the discovery of a wide retrograde moving group in the disk plane of the Milky Way using action-angle coordinates derived from the \textit{Gaia} DR3 catalog. The structu…
Typhon: a polar stream from the outer halo raining through the Solar neighborhood
Wassim Tenachi, Pierre-Antoine Oria, Rodrigo Ibata +5
We report on the discovery in the Gaia DR3 astrometric and spectroscopic catalog of a new polar stream that is found as an over-density in action space. This structure is unique as…
Revisiting a disky origin for the faint branch of the Sagittarius stellar stream
Pierre-Antoine Oria, Rodrigo Ibata, Pau Ramos +2
We investigate ways to produce the bifurcation observed in the stellar stream of the Sagittarius dwarf galaxy (Sgr). Our method consists in running -body simulations of Sgr fall…
On the Effect of the Large Magellanic Cloud on the Orbital Poles of Milky Way Satellite Galaxies
Marcel S. Pawlowski, Pierre-Antoine Oria, Salvatore Taibi +2
The reflex motion and distortion of the Milky Way (MW) halo caused by the infall of a massive Large Magellanic Cloud (LMC) has been demonstrated to result in an excess of orbital p…
Probing the radial acceleration relation and the strong equivalence principle with the Coma cluster ultra-diffuse galaxies
J. Freundlich, B. Famaey, P. -A. Oria +3
The tight radial acceleration relation (RAR) obeyed by rotationally supported disk galaxies is one of the most successful a priori predictions of the modified Newtonian dynamics (M…
