Hi everyone,

Following on from Jamie's email, Arghyadeep will be giving a lunch talk on Thursday at 1pm in A113. The title and abstract of the talk are below.

Impacts of Non-stellar Sources on IGM : Interpretation of Lyman-¨» forest observations
The Epoch of Reionization (EoR) marks a critical phase in the evolution of the universe, yet remains poorly understood. While star-forming galaxies are acknowledged as key contributors to ionized bubble formation, the extent of contribution from alternative sources such as shock-heated ISM or emission from X-ray binaries remains unclear. In this study, we employ cosmological radiative transfer simulations to explore the impact of diverse sources on intergalactic medium (IGM) properties. Our focus is not merely data fitting, but rather understanding whether the interpretation of Lyman-¨» forest observations is changed by using theoretical models incorporating non-stellar sources. By decoupling various sources, we also aim to discern their individual contributions to the reionization process. In this presentation, I¡¯ll discuss our simulation methodology and initial insights into our findings.

Thanks,
Harry.
