Hot or Cold? Radial Redistribution of Stars in FIRE Simulations of Milky Way-Mass Galaxies and the Asymmetry of Inward versus Outward Migrators
Cecilia Steel, Andrew Wetzel, Rori Kang +3
Stars can radially redistribute (migrate) within galactic disks. The degree to which this occurs as dynamically `cold' (preserves orbital eccentricity) or `hot' (increases eccentri…
Radial redistribution of stellar orbits in FIRE simulations of Milky-Way-mass galaxies
Matthew A. Bellardini, Fiona McCluskey, Andrew Wetzel +3
A central question in galactic dynamics and galactic archeology is: how much do the orbits of stars redistribute (migrate) after birth? We use the FIRE-2 cosmological zoom-in simul…
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…
Spiral Structure Properties, Dynamics, and Evolution in MW-mass Galaxy Simulations
J. R. Quinn, S. R. Loebman, K. J. Daniel +8
The structure of spiral galaxies is essential to understanding the dynamics and evolution of disk galaxies; however, the precise nature of spiral arms remains uncertain. Two challe…
Stellar Velocity Dispersion versus Age: Consistency across Observations and Simulations, with the Milky Way as an Outlier
Fiona McCluskey, Andrew Wetzel, Sarah Loebman +1
Within disk galaxies, the velocity dispersion, , of stars increases with age, , as measured in the Milky Way (MW) and nearby galaxies. This relation provides a key window int…
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…
Disk settling and dynamical heating: histories of Milky Way-mass stellar disks across cosmic time in the FIRE simulations
Fiona McCluskey, Andrew Wetzel, Sarah R. Loebman +3
We study the kinematics of stars both at their formation and today within 14 Milky Way (MW)-mass galaxies from the FIRE-2 cosmological zoom-in simulations. We quantify the relative…
When Cold Radial Migration is Hot: Constraints from Resonant Overlap
Kathryne J. Daniel, David A. Schaffner, Fiona McCluskey +2
It is widely accepted that stars in a spiral disk, like the Milky Way's, can radially migrate on order a scale length over the disk's lifetime. With the exception of cold torquing,…
