Intensity mapping: a new window into the cosmos
 
 

The technique of intensity mapping (IM) has emerged as a powerful tool to explore the universe at z < 6. IM measures the integrated emission from sources over a broad range of frequencies, unlocking significantly more information than traditional galaxy surveys. Astrophysical uncertainties, however, constitute an important systematic in our attempts to constrain cosmology with IM. The speaker will describe an innovative approach which allows us to fully utilize our current knowledge of astrophysics in order to develop cosmological forecasts from IM. This framework can be used to exploit synergies with other complementary surveys, thereby opening up the fascinating possibility of constraining physics beyond LCDM from future IM observations.
