Radio Galaxy Zoo: Knowledge Transfer Using Rotationally Invariant Self-Organising Maps

T. J. Galvin, M. Huynh, R. P. Norris +7

With the advent of large scale surveys the manual analysis and classification of individual radio source morphologies is rendered impossible as existing approaches do not scale. Th…
