I was wondering the same! Helpful to know this. Another thing that we’ll have to get people to unlearn 🙁

Lovely! But, if only our EDGE2 paper had been out in time that figure 4 would’ve looked so much better…

As things stand, the baryon acoustic oscillations strongly favour boring old dark energy.

Hmmm… mixed feelings on that one
