Earlier this year, ALMA saw its receiver complement extended with the installation of the last Band 5 receivers. These receivers were built by a European consortium consisting of the Nederlandse Onderzoekschool voor Astronomie (NOVA) and the Group for Advanced Receiver Development (GARD). The first science results with this brand new receiver are already starting to appear. One exciting result is the detection of a radioactive molecule in CK Vulpeculae, which heavily relied on ALMA Band 5, as well as the discovery with the prototype Band 5 receiver at APEX.
