The University of Tokyo), Bunkyo-ku, Tokyo, Japan, The anomalous microwave emission (AME) still lacks a conclusive explanation. This excess of emission, roughly between 10 and 50 GHz, correlates spatially with interstellar dust, prompting a 'spinning dust' hypothesis: electric dipole emission by rapidly rotating, small dust grains. The typical peak frequency range of the AME profile implicates grains on the order of 1 nm, suggesting polycyclic aromatic hydrocarbon molecules (PAHs). We compare AKARI/Infrared Camera (IRC), with its thorough PAH-band coverage, to AME intensity estimates from the Planck Collaboration, in the lambda Orionis region. We look also at infrared dust emission from other mid IR and far-IR bands. The results and discussion contained here apply to an angular scale of approximately 1 deg. In general, our results support an AME-from-dust hypothesis. In lambda Orionis, we find that certainly dust mass correlates with AME, and that PAH-related emission in the AKARI/IRC 9 micrometers band may correlate slightly more strongly., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730026018, レポート番号: JAXA-SP-17-009E}, pages = {123--126}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {A look at possible microwave dust emission via AKARI infrared all-sky surveys}, volume = {JAXA-SP-17-009E}, year = {2018} }
