Radio Galaxy Classification: #Tags, Not Boxes

After six decades of studying radio galaxies, we are now delightfully overwhelmed by their exponentially expanding numbers and the complexity structures. Similarly, methods use to classify galaxies have exploded, often resulting in conflicting terminology, ambiguous classifications, historical schemes that may or not match our current physical understanding. discussions with more than 100 astronomers over last several years listening ideas aspirations, I propose reconceptualize classification galaxies. Instead trying place them into “boxes”, should assign #tags, a system is easy understand apply, flexible evolving, can accommodate respect what relevant important. Here, outline basis such #tag system; rest up community.
