Spiral Morphology and Radial Migration: Kinematically heating, cooling, and cold
Kathryne J. Daniel, M. E. Wisz, Karen L. Masters +3
Transient spiral arms are known to drive radial redistribution of stars and thus could play a central role in shaping disk galaxies, including modifying, over time, the age, chemic…
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…
Wrinkles in Time. II. Stellar Age Trends in Kinematic Signatures from Transient Spiral Structure
Amy Smock, Kathryne J. Daniel, Rayna Rampalli +4
Spiral arms in the disks of galaxies like the Milky Way can generate kinematic signatures, which appear as ridges or wrinkles in action space. Such signatures have proven difficult…
