The Dynamics of Old Inner Galaxy Stars in Milky Way-mass Galaxies Using FIRE-2 Simulations
Emma Tasso, Madeline Lucey, Robyn Sanderson +2
Understanding how galaxies like the Milky Way assembled over cosmic time remains a central question in astrophysics. Understanding the processes that shaped their formation and evo…
Probing Atomic Dark Matter with Stellar Streams in Milky Way-Mass Galaxies
Lucas S. Mandacarú Guerra, Stephanie O'Neil, Mariangela Lisanti +7
We present the first detailed analysis of the effects of dissipative dark matter on stellar streams. As a concrete example, we generate a cosmological hydrodynamic zoom-in simulati…
Rise of the forsaken relics: connecting present-day stellar streams and phase-mixed galaxies to the Epoch of Reionization
Aritra Kundu, Robyn Sanderson, Adam Lidz +6
The `near-far' approach to studying reionization leverages the star formation histories of the Milky Way (MW) or Local Group (LG) galaxies, derived from resolved photometry, to inf…
Cosmological predictions for minor axis stellar density profiles in the inner regions of Milky Way-mass galaxies
Madeline Lucey, Robyn Sanderson, Danny Horta +5
CDM cosmology predicts the hierarchical formation of galaxies which build up mass by merger events and accreting smaller systems. The stellar halo of the Milky Way has proven t…
