Central stellar depletion in the Draco dwarf from Subaru photometry
Eduardo Vitral, Kyosuke S. Sato, Jorge Peñarrubia +2
Dark matter subhaloes are a fundamental prediction of the standard cosmological model, but their low-mass population remains difficult to constrain observationally. Recent work has…
Dynamical friction vs. subhalo heating in Cold Dark Matter haloes
Jorge Peñarrubia, Pierfrancesco Di Cintio, Eduardo Vitral +1
The orbital evolution of massive stellar systems embedded in dark matter haloes is governed by competing processes. Dynamical friction removes orbital energy, whereas fluctuations…
Neighbors, Not Kin: Kinematic evidence for tidal tails from NGC 7492 along the Sagittarius stream
Camila Navarrete, Álvaro Rojas-Arriagada, Andrés E. Piatti +8
The formation, extension, and morphology of extra-tidal stars around globular clusters depend on the internal kinematics of the host cluster and the Galactic potential. Tracing the…
Structural Diversity Among the Milky Way's Dwarf Spheroidal Satellites
Matthew G. Walker, Raphaël Errani, Andrew B. Pace +3
We fit a flexible double power-law (`') model to the stellar density fields observed for the Milky Way's known dwarf spheroidal satellite galaxies. We show that where standard…
Reconstructing the orbits of Milky Way dwarf galaxies: A Large Magellanic Cloud perspective
Alberto Manuel Martínez-García, Andrés del Pino, Roeland P. van der Marel +14
The orbital histories of the dwarf satellites of the Milky Way (MW) are key to understanding their evolution and placing their present-day properties in a dynamical context. We pre…
Hubble Astrometry for the Local Group and Beyond in the 2030s
S. Tony Sohn, Paul Bennet, Kevin Andrew McKinnon +23
Hubble's long, stable astrometric baseline creates a rare opportunity for discovery in the Local Group and beyond. Many nearby galaxies, streams, and star clusters already have arc…
