A high-resolution line survey of IRC +10216 with Herschel/HIFI *,** First results: Detection of warm silicon dicarbide (SiC)
carbon-rich evolved star IRC+10216
2014/12/20
We present the first results of a high-spectral-resolution survey of the carbon-rich evolved star IRC+10216 that was carried out with the HIFI spectrometer onboard Herschel. This survey covers all HIF...
LINEAR POLARIZATION AND TOTAL FLUX DENSITY OF SILICON MONOXIDE MASERS AND ACTIVE EXTRAGALACTIC OBJECTS AT MILLIMETER WAVELENGTHS
Millimeter-wave wireless resources Linear polarization Radio astronomy observatory telescope Maser The Milky Way
2014/12/10
In order to investigate the linear polarization properties of millimeter-wave radio sources, a polarimeter was constructed for use on the Five College Radio Astronomy Observatory 14m telescope. Linear...
The impact of spatial fluctuations in the ultra-violet background on intergalactic carbon and silicon
methods: numerical intergalactic medium quasars absorption lines
2010/11/12
Spatial inhomogeneities in the spectral shape of the ultra-violet background (UVB) at the tail-end of He II reionisation are thought to be the primary cause of the large fluctuations observed in the H...
