Are all starbursts equal? Star-formation-rate profiles in merger versus secular starbursts
Mallory D. Thorp, Sara L. Ellison, Ana Galicia
Galaxy interactions can trigger drastic changes in the resolved star-forming properties of their constituents, but it remains unclear as to whether those changes are discernible fr…
