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…
