Anomalous Microwave Emission from Very Small Dust Grains

Presenter: Anna Scaife (University of Manchester)

The emission spectrum of the anomalous microwave emission (AME) thought to arise from rapidly rotating very small dust grains, known as "spinning dust", will be well probed by ALMA Band 1. The combined frequency coverage and sensitivity of these new receivers will consequently provide an excellent resource for studying known sources of AME, as well as making new discoveries. Here I will review the evidence for this novel continuum emission mechanism, discuss the potential physical constraints provided by existing observations, both Galactic and extra-galactic, and highlight areas where ALMA Band 1 can be instrumental in uncovering the properties of astrophysical media that give rise to this still elusive emission.
