Does the CMB prefer a leptonic universe? — published

The latest article of Dominik Schwarz and me is published. You can find it here. We were invited to publish it in the New Journal of Physics, which has a nice concept: the writer has to pay for publishing. The benfit for you as a reader is, that all articles are open acces. Moreover, we also shot a video abstract as a small appetizer to our idea that the cosmic microwave background observations prefer anti-neutrinos. If you like science the more “classical” way without videos but still free, you can also find our article on the arXiv.
