Studies of Anomalous Microwave Emission (AME) with the SKA
  In this chapter, we will outline the scientific motivation for studying
Anomalous Microwave Emission (AME) with the SKA. AME is thought to be due to
electric dipole radiation from small spinning dust grains, although thermal
fluctuations of magnetic dust grains may also contribute. Studies of this
mysterious component would shed light on the emission mechanism, which then
opens up a new window onto the interstellar medium (ISM). AME is emitted mostly
in the frequency range $\sim 10$--100\,GHz, and thus the SKA has the potential
of measuring the low frequency side of the AME spectrum, particularly in band
5. Science targets include dense molecular clouds in the Milky Way, as well as
extragalactic sources. We also discuss the possibility of detecting rotational
line emission from Poly-cyclic Aromatic Hydrocarbons (PAHs), which could be the
main carriers of AME. Detecting PAH lines of a given spacing would allow for a
definitive identification of specific PAH species.
