cds-question@unistra.frsurveysradio-continuum-emissioninterstellar-mediumpolarimetryDetermining the spectral and spatial characteristics of the radio continuum of our Galaxy is an experimentally challenging endeavour for improving our understanding of the astrophysics of the interstellar medium. This knowledge has also become of paramount significance for cosmology, since Galactic emission is the main source of astrophysical contamination in measurements of the Cosmic Microwave Background radiation. In this paper we present the scope of the Galactic Emission Mapping (GEM) project and its results at 2.3GHz. Its observational program was conceived and developed to reveal the large scale properties of Galactic synchrotron radiation in total intensity and polarisation through a self-consistent set of radio continuum surveys between 408MHz and 10GHz. GEM's unique observational strategy and experimental design aim at the production of foreground templates in order to address the mutual inconsistencies between existing surveys.2013A&A...556A...1Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/556/A1CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/556/A1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/556/A1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/556/A1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/556/A1https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/556/A1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/556/A1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefault
