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…
The Debris of the "Last Major Merger" is Dynamically Young
Thomas Donlon, Heidi Jo Newberg, Robyn Sanderson +4
The Milky Way's (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the "last major merger." Hypotheses for the origin of t…
Testing the near-far connection with FIRE simulations: inferring the stellar mass function of the proto-Local Group at z > 6 using the fossil record of present-day galaxies
Pratik J. Gandhi, Andrew Wetzel, Michael Boylan-Kolchin +6
The shape of the low-mass (faint) end of the galaxy stellar mass function (SMF) or ultraviolet luminosity function (UVLF) at z > 6 is an open question for understanding which galax…
Bar formation and destruction in the FIRE-2 simulations
Sioree Ansar, Sarah Pearson, Robyn E. Sanderson +5
The physical mechanisms responsible for bar formation and destruction in galaxies remain a subject of debate. While we have gained valuable insight into how bars form and evolve fr…
LMC-driven anisotropic boosts in stream--subhalo interactions
Arpit Arora, Nicolás Garavito-Camargo, Robyn E. Sanderson +4
Dark Matter (DM) subhalos are predicted to perturb stellar streams; stream morphologies and dynamics can constrain the mass distribution of subhalos. Using FIRE-2 simulations of Mi…
Modeling the orbital histories of satellites of Milky Way-mass galaxies: testing static host potentials against cosmological simulations
Isaiah B. Santistevan, Andrew Wetzel, Erik Tollerud +3
Understanding the evolution of satellite galaxies of the Milky Way (MW) and M31 requires modeling their orbital histories across cosmic time. Many works that model satellite orbits…
