Description
The epoch of reionisation marks the emergence of the first galaxies that emit light into the intergalactic medium, leading to the ionisation and heating of the Universe. This phase is a forefront area in astrophysics. While our current understanding relies on theoretical models of early galaxy formation within the standard cold dark matter (CDM) cosmology, recent observations, including early galaxy data from the James Webb Space Telescope (JWST) and the thermal evolution of intergalactic gas from the Experiment to Detect the Global EoR Signature (EDGES), have raised questions about this conventional view. I will present our initial testing of models using JWST observations of early galaxies and discuss the potential for further insights with upcoming observations.
