Research summary
AI-generated

Heyang Long works in cosmology and astrophysics, focusing on the early universe's 'reionization' era (when the first stars and galaxies ionized surrounding gas), using signals like the 21-cm radio signal from hydrogen gas and the Lyman-alpha forest (light absorption patterns from distant quasars) to study cosmic history and dark matter. This research combines theoretical modeling, radiative transfer simulations, and forecasts for future surveys such as the Roman Space Telescope. Prospective students would likely engage with simulation-based and data-analysis approaches to probing the structure and composition of the early universe.

Publication output was low and sporadic from 2017-2021 but increased notably from 2022 onward, peaking in 2023, suggesting a growing and currently active research output.
