We find that the likelihood of having a bar, or bulge, in disc galaxies increases when the galaxies have redder (optical) colours and larger stellar masses, and observe a transition in the bar and bulge likelihoods, such that massive disc galaxies are more likely to host bars and bulges. We use galaxy clustering methods to demonstrate statistically signif","authors_text":"Ben Hoyle, Carolin N. Cardamone, Chris Lintott, Edward M. Edmondson, Idit Zehavi, Karen L.
