The GEM 2.3 GHz Receiver System
GEM 2.3 GHz Rationale
The frequency 2.3 GHz was chosen because the Galaxy produces significant
radiation there, it fit nicely in our set of frequencies and there was
an ongoing southern sky map
(Rhodes Sky Survey by Justin Jonas et al.)
at reasonably good resolution. There are few sky surveys and the
southern sky is particularly sparsely mapped.
A check and calibration at 2.3 GHz and link to the northern sky
could make the ongoing survey much more valuable.
A GEM success could lead to a significant destriping of these data.
Reports on the 2.3 GHz Receiver
The project has been supported in part by the US Department of Energy,
by the US National Science Foundation, by the Progetto Italia Antartide,
by INPE-Brazil, and by Colciencias of Colombia.
Some of the publications to date are on the following
GEM publication list.
