The Nancy Grace Roman Space Telescope ( Roman ) is set to launch in May 2027 .

During the formative years of the universe, it was filled with a hot, dense sea of particles, including free electrons.

This negatively charged particles endlessly scattered photons, making the universe opaque.

The removal of free electrons allowed the first light to travel through the universe.

The question is: What caused this ionization of neutral atoms?.

WST is finding far more quasars than expected as it probes cosmic dawn.

These active supermassive black hole regions are known as active galactic nuclei.

WST has been discovering them at distances that correspond to a period of less than one billion years after the Big Bang .

One question that researchers will be trying to answer with Roman is what type of galaxies were responsible for ionizing radiation at cosmic dawn..
