Properly characterizing Galactic emission is vital to the future of Cosmic Microwave Background (CMB) science. Though synchrotron and thermal dust emission usually take front stage in polarization, anomalous microwave emission (AME) certainly cannot be discounted as a potential contaminant. Such an assumption could complicate future and current CMB studies. A preprint of this work can be found here.
