Understanding the Origin and Dynamical Evolution of the Unique Open Star Cluster Berkeley 20 using FIRE Simulations
Alessa I. Wiggins, Jamie R. Quinn, Micah Oeur +11
Open clusters (OCs) act as key probes that can be leveraged to constrain the formation and evolution of the Milky Way (MW)'s disk, as each has a unique chemical fingerprint and wel…
OTI on FIRE: Testing the Efficacy of Orbital Torus Imaging to Recover the Galactic Potential
Micah Oeur, Sarah R. Loebman, Adrian M. Price-Whelan +3
Orbital Torus Imaging (OTI) is a dynamical inference method for determining the Milky Way's gravitational potential using stellar survey data. OTI uses gradients in stellar astroph…
Decoding the Galactic Twirl: The Downfall of Milky Way-mass Galaxies Rotation Curves in the FIRE Simulations
Xiaowei Ou, Lina Necib, Andrew Wetzel +3
Recent measurements of the Milky Way rotation curve found a sharp decline at around - kpc from the center of the Galaxy, suggesting that the Galactic dark matter halo is mu…
The imprint of dark matter on the Galactic acceleration field
Arpit Arora, Robyn E. Sanderson, Sukanya Chakrabarti +6
Measurements of the accelerations of stars enabled by time-series extreme-precision spectroscopic observations, from pulsar timing, and from eclipsing binary stars in the Solar Nei…
