Anomalous emission from HII regions
Spinning dust appears to be the best explanation for the anomalous emission that has been observed at ∼ 10 − 60 GHz. One of the best examples of spinning dust comes from a HII region in the Perseus molecular cloud. Observations of other HII regions also show tentative evidence for excess emission at frequencies ∼ 30 GHz, although at lower emissivity levels. A new detection of excess emission at...
متن کاملMz Inequalities and Interpolation 3
We find necessary density conditions for Marcinkiewicz-Zygmund inequalities and interpolation for spaces of spherical harmonics in S with respect to the L norm. Moreover, we prove that there are no complete interpolation families for p 6= 2.
متن کاملExtended Anomalous Foreground Emission in the Wmap 3-year Data
We study the spectral and morphological characteristics of the diffuse Galactic emission in the WMAP temperature data using a template-based multi-linear regression, and obtain the following results. 1. We confirm previous observations of a bump in the dust-correlated spectrum, consistent with the Draine & Lazarian spinning dust model. 2. We also confirm the “haze” signal in the inner Galaxy, a...
متن کاملAnomalous Radio Emission from Dust in the Helix
A by-product of experiments designed to map the cosmic microwave background is the recent detection of a new component of foreground Galactic emission. The anomalous foreground at 10–30 GHz, unexplained by traditional emission mechanisms, correlates with 100 m dust emission. We use planetary nebulae (PNs) as astrophysical laboratories to test known radio emission processes and report that in th...
متن کاملANOMALOUS MICROWAVE EMISSION FROM THE Hii REGION RCW175
We present evidence for anomalous microwave emission in the RCW175 Hii region. Motivated by 33 GHz 13 resolution data from the Very Small Array (VSA), we observed RCW175 at 31 GHz with the Cosmic Background Imager (CBI) at a resolution of 4. The region consists of two distinct components, G29.0-0.6 and G29.1-0.7, which are detected at high signal-to-noise ratio. The integrated flux density is 5...
