The Reliability of Galaxy Classifications by Citizen Scientists
229th American Astronomical Society Meeting, Grapevine, Texas, January 3-7, 2017
Citizen scientists are becoming more and more important in helping professionals working through big data. An example in astronomy is crowdsourced galaxy classification. But how reliable are these classifications for studies of galaxy evolution? We present a tool in order to investigate those morphological classifications and test it on a diverse population on our campus. We observe a slight offset towards earlier Hubble types in the crowdsourced morphologies, when compared to professional classifications.
