Anomalous Microwave Emission: Theory, Modeling, and Observations


It is now generally accepted that anomalous microwave emission—an emission peaking in the range 20-60 GHz correlating with infrared emission—is an additional radiation component of the interstellar medium. This emission is present both in the diffuse medium and in discrete sources, such as molecular clouds and HII regions, and it is commonly attributed to very small rotating dust particles. Unveiling the precise nature of this component of emission is crucial not only to improve the modeling of foregrounds for future cosmic microwave background experiments, but also to expand our knowledge of astrophysical dust grains. In very recent years, a strong impulse to the investigation of anomalous microwave emission has come from the wealth of data provided by first-class space facilities such as Planck, Spitzer, and Herschel. The availability of this unprecedented amount of data has been accompanied by a “burst” of theoretical and modeling activity.

We invite original contributions, as well as review articles, discussing the most recent results in the field of anomalous microwave emission. In particular, we encourage the submission of both theoretical articles making accurate predictions regarding the potential carriers of this radiative mechanism and the optimal physical conditions where it can manifest itself and articles describing the latest advances in the observational domain. Potential topics include, but are not limited to:

  • Recent developments of theory and modeling tools
  • Latest results from observations, both from space missions and ground-based experiments
  • Advances in modeling of the dust properties in regions characterized by significant amount of anomalous emission
  • The extragalactic view of anomalous microwave emission: the case of NGC 6946 and low-metallicity dwarf galaxies
  • Historical perspective: key data which have shown the existence of the anomalous microwave emission
