The fact that we found the Wolfe Disk using this method, tells us that it belongs to the normal population of galaxies present at early times, when our newest observations with ALMA surprisingly showed that it is rotating, we realized that early rotating disk galaxies are not as rare as we thought and that there should be a lot more of them out there. Thanks to ALMA, we now have unambiguous evidence that they occur as early as 1.5 billion years after Big Bang.
