Dominant Role of Coplanar Inflows in Driving Disk Evolution Revealed by Gas-phase Metallicity Gradients

Using spatially resolved spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory sample, we investigate the parameters influencing the radial gradients of gas-phase metallicity ( ${\rm{\nabla }}\mathrm{log}({\rm{O}}/{\rm{H}})$ ) to determine whether disk formation is primaril...
