The Physical Drivers and Observational Tracers of CO-to-H2 Conversion Factor Variations in Nearby Barred Galaxy Centers

The CO-to-H _2 conversion factor ( α _CO ) is central to measuring the amount and properties of molecular gas. It is known to vary with environmental conditions, and previous studies have revealed lower α _CO in the centers of some barred galaxies on kiloparsec scales. To unveil the physical drivers...
