During the Epoch of Reionisation (EoR), the Universe went from being dark and neutral to mostly ionised at z~6. The sources responsible for ionising the intergalactic medium (IGM) are thought to be mainly the first stars and galaxies, until now observationally elusive. With the arrival of JWST data, we have now unprecedented access to the early Universe, which can be used to improve our current models and understanding of this epoch.
This is a one-day meeting that will bring together experts studying the EoR from different perspectives and scales: from the young stars that produce copious amounts of ionising radiation, to the galaxies that contain them, and the surrounding IGM. The meeting will be broadly divided into three topics, and what we can learn about the EoR through them. Each session will start with a review talk by an invited speaker, as follows:
| Session | Guest speaker | University |
| Galaxies | Aayush Saxena | University of Oxford |
| IGM | Laura Keating | University of Edinburgh |
| Simulations | Harley Katz | University of Oxford |
Some suggested topics include (but are not limited to): properties of galaxies at the EoR, escape fractions, SED modelling, mechanisms that produce ionising photons, reionisation as studied by QSO absorption lines, and redshift evolution of volume-averaged escape fractions.
We aim to have a balance between observational and theoretical results, as well as to balance speakers from all career stages, so we strongly encourage scientists from all career stages to submit an abstract.
