CMBPol Mission Concept Study: Prospects for polarized foreground removal
J. Dunkley, A. Amblard, C. Baccigalupi +28
In this report we discuss the impact of polarized foregrounds on a future CMBPol satellite mission. We review our current knowledge of Galactic polarized emission at microwave freq…
Centimeter-wave continuum radiation from the rho Ophiuchi molecular cloud
Simon Casassus, Clive Dickinson, Kieran Cleary +8
The rho Oph molecular cloud is undergoing intermediate-mass star formation. UV radiation from its hottest young stars heats and dissociates exposed layers, but does not ionize hydr…
Anomalous Emission from HII regions
C. Dickinson
Spinning dust appears to be the best explanation for the anomalous emission that has been observed at GHz. One of the best examples of spinning dust comes from a HII r…
Component separation methods for the Planck mission
S. M. Leach, J. -F. Cardoso, C. Baccigalupi +27
The Planck satellite will map the full sky at nine frequencies from 30 to 857 GHz. The CMB intensity and polarization that are its prime targets are contaminated by foreground emis…
Radio source calibration for the VSA and other CMB instruments at around 30 GHz
Yaser A. Hafez, Rod D. Davies, Richard J. Davis +20
Accurate calibration of data is essential for the current generation of CMB experiments. Using data from the Very Small Array (VSA), we describe procedures which will lead to an ac…
A centimetre-wave excess over free-free emission in planetary nebulae
S. Casassus, L. -A. Nyman, C. Dickinson +1
We report a centimetre-wave (cm-wave, 5-31GHz) excess over free-free emission in PNe. Accurate 31 and 250GHz measurements show that the 31GHz flux densities in our sample are syste…
