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…
Interstellar 12C/13C from CH+ absorption lines: Results from an extended survey
O. Stahl, S. Casassus, T. L. Wilson
The 12C/13C isotope ratio in the interstellar medium (ISM), and its evolution with time, is an important tracer of stellar yields. Spatial variations of this ratio can be used to s…
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…

CBI limits on 31 GHz excess emission in southern HII regions
C. Dickinson, R. D. Davies, L. Bronfman +5
We have mapped four regions of the southern Galactic plane at 31 GHz with the Cosmic Background Imager. From the maps, we have extracted the flux densities for six of the brightest…
An upper limit on anomalous dust emission at 31 GHz in the diffuse cloud [LPH96]201.663+1.643
C. Dickinson, S. Casassus, J. L. Pineda +3
[LPH96]201.663+1.643, a diffuse H{\sc ii} region, has been reported to be a candidate for emission from rapidly spinning dust grains. Here we present Cosmic Background Imager (CBI)…
