Cosmic Dawn Intensity Mapper

Understand

Cosmic Dawn Intensity Mapper is a "Probe Class" mission concept for reionization studies of the universe.

• It will be capable of spectroscopic imaging observations between 0.7 to 6-7 microns in the near-Infrared.
• The primary observational objective is pioneering observations of spectral emission lines of interest throughout the cosmic history, but especially from the first generation of distant, faint galaxies when the universe was less than 800 million years old.
• With spectro-imaging capabilities, using a set of linear variable filters (LVFs), CDIM will produce a three-dimensional tomographic view of the epoch of reionization (EoR).
