Galactic Emission from Spinning Dust Grains
Spinning interstellar dust grains produce detectable rotational emission in the 10-100 GHz frequency range. We calculate the emission spectrum, and show that this emission can account for the " anomalous " Galactic background component which correlates with 100 µm thermal emission from dust. Implications for cosmic background studies are discussed.

متن کاملA Broadband Study of Galactic Dust Emission
We have combined infrared data with HI , H2 and HII surveys in order to spatially decompose the observed dust emission into components associated with different phases of the gas. An inversion technique is applied. For the decomposition, we use the IRAS 60 and 100 µm bands, the DIRBE 140 and 240 µm bands, as well as Archeops 850 and 2096 µm wavelengths. In addition, we apply the decomposition t...
متن کاملHerschel observations of the Sagittarius B2 cores: Hydrides, warm CO, and cold dust ⋆
Context. Sagittarius B2 is one of the most massive and luminous star-forming regions in the Galaxy and shows a very rich chemistry and physical conditions similar to those in much more distant extragalactic starbursts. Aims. We present large-scale far-infrared/submillimeter photometric images and broadband spectroscopic maps taken with the PACS and SPIRE instruments onboard Herschel. Methods. H...
متن کاملMicrowave Emission from Galactic Dust Grains
Observations of the cosmic microwave background have revealed a component of 10–60 GHz emission from the Galaxy which correlates with 100–140μm emission from interstellar dust but has an intensity much greater than expected for the low-frequency tail of the “electric dipole vibrational” emission peaking at ∼130μm. This “anomalous emission” is more than can be accounted for by dust-correlated fr...
