SUMMARY:Spiral Arm–Driven Star Formation in the FIRE Simulations\, P
 reliminary Exam\, Hannah Woodward
DESCRIPTION:Recent observations have traced the trajectories of nearby
  star clusters backward in time\, revealing that many have converging 
 paths and likely shared common origins. This trend spans clusters acro
 ss a wide range of ages\, providing evidence for sequential star forma
 tion. While stellar feedback is often invoked to explain such propagat
 ion\, the dynamics of spiral arms may also compress gas and trigger ne
 w star formation. To explore this mechanism\, we searched for signatur
 es of spiral arm–induced star formation in the Feedback In Realistic
  Environments (FIRE) simulations. We applied the HDBSCAN clustering al
 gorithm to identify groups of star particles with similar positions an
 d velocities within selected regions of a simulated galaxy\, and then 
 analyzed their kinematic evolution over time. I will compare the motio
 ns of FIRE star particles to the observed trajectories of nearby stell
 ar clusters to investigate whether spiral structure can drive sequenti
 al star formation.
