And still, it rotates!

This week the Smit et al paper on the kinematics of galaxies at z~7 (!) with ALMA went to Nature Astronomy (https://arxiv.org/abs/1706.04614). Yay Renske! And today this totally apt XKCD came out:The joke being that it is very tricky to interpret a kinematic map at any redshift. One of the big unseen efforts in the paper was the team's discussion on the interpretation of the kinematic data.It does look like it could well be rotating. This is a very exciting result. Hopefully more kinematic data of such galaxies can be obtained. Then we can compare the results to those of populations of galaxies at later epochs (two isn't exactly a statistical sample yet, although at this redshift it almost is).
