A New Paper All About #yellowballs

Another paper for the Milky Way Project. The Yellowballs began on the very first day of the Milky Way Project when a user asked me ‘what is this?’ and I wasn’t sure so jokingly called it a ‘#yellowball’, since that’s what is looked like. We use hashtags on talk.milkywayprojct.org, and that user, and a few others, went off and tagged hundreds of the things over the next few months. Before we knew it there was a catalogue of them. However, we still didn’t know what they really were, and so Grace Wolf-Chase, Charles Kerton, and other MWP collaborators have put a lot of effort into figuring it out. The result is this new paper.
