ReIonization and Signatures of Early Stars
Understanding how the first stars and galaxies formed and drove the Universe's final phase transition by re-ionizing intergalactic hydrogen is one of the long-standing goals of extragalactic astronomy. In the past two decades, we have discovered this ``Epoch of Reionization'' ended around one billion years after the Big Bang (redshift, z < 6), but the process is still poorly understood. We are currently undergoing a radical shift in our ability to observe this epoch with the new James Webb Space Telescope (JWST). Early JWST observations have discovered a surprising excess of luminous z > 9 galaxies, implying stars may have formed differently in the early universe than we had previously…
