EIGER

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
