Exploring the direct connections between galaxies and the intergalactic gas back to the reionization epoch

To achieve this key goal, EIGER carries out deep and complete surveys with JWST for emission-line galaxies in the fields of high-redshift luminous quasars, where we can learn the state of the intervening gaseous material along the lines of sight using the quasars' deep high-resolution spectra. The primary science goals include

  • Reionization and the roles of galaxies
  • The identification of the host systems of metal absorber and the state of the CGM
  • The nature of the host galaxies and environments of the earliest quasars
  • The blackhole masses and systemic redshifts of the earliest quasars
