Orbital Torus Imaging: Acceleration, density, and dark matter in the Galactic disk measured with element abundance gradients

Danny Horta, Adrian M. Price-Whelan, David W. Hogg +5

Under the assumption of a simple and time-invariant gravitational potential, many Galactic dynamics techniques infer the Milky Way's mass and dark matter distribution from stellar…

On the co-rotation of Milky Way satellites: LMC-mass satellites induce apparent motions in outer halo tracers

Nicolas Garavito-Camargo, Adrian M. Price-Whelan, Jenna Samuel +8

Understanding the physical mechanism behind the formation of a co-rotating thin plane of satellite galaxies, like the one observed around the Milky Way (MW), has been challenging.…

Chemical Cartography of the Sagittarius Stream with Gaia

Emily C. Cunningham, Jason A. S. Hunt, Adrian M. Price-Whelan +5

The stellar stream connected to the Sagittarius (Sgr) dwarf galaxy is the most massive tidal stream that has been mapped in the Galaxy, and is the dominant contributor to the outer…

The proto-galaxy of Milky Way-mass haloes in the FIRE simulations

Danny Horta, Emily C. Cunningham, Robyn Sanderson +9

Observational studies are finding stars believed to be relics of the earliest stages of hierarchical mass assembly of the Milky Way (i.e., proto-Galaxy). In this work, we contextua…

Prospects for Detecting Gaps in Globular Cluster Stellar Streams in External Galaxies with the Nancy Grace Roman Space Telescope

Christian Aganze, Sarah Pearson, Tjitske Starkenburg +5

Stellar streams form through the tidal disruption of satellite galaxies or globular clusters orbiting a host galaxy. Globular cluster streams are exciting since they are thin (dyna…

Constraining the Gravitational Potential from the Projected Morphology of Extragalactic Tidal Streams

Jacob Nibauer, Ana Bonaca, Kathryn V. Johnston

The positions and velocities of stellar streams have been used to constrain the mass and shape of the Milky Way's dark matter halo. Several extragalactic streams have already been…
