From Raul Jimenez, the lead author of this paper.
Dear galaxy zooers,

Our paper on the correlation of spins and past star formation was  accepted today to the MNRAS. This was after a very positive and  insightful referee report, which helped us make the paper stronger.  next steps are to look for the effect in numerical simulations and  increase the size of the observational sample. Because the above  correlation is a very particular prediction of hierarchical galaxy  formation, it raises the bar for alternative theories of galaxy formation to produce such effect.
