Bubbles in the early Universe

Happening less than a billion years after the Big Bang, the formation of the first luminous sources, such as the first stars and galaxies, characterises the Cosmic Dawn. This led to the Epoch of Reionisation (EoR), the last major phase change of the hydrogen atoms in the Universe when the intense UV radiation produced by the first stars ionised them and had a lasting impact on all subsequent galaxy formation and evolution. With the recent launch of JWST and upcoming facilities such as the Square Kilometer Array, astronomy is poised to make huge strides in the elucidation of the important astrophysical recipes of these exciting periods. In this talk, I will give a basic introduction to the (astro)physics of the EoR and my contribution to the making realistic simulations of this exciting period.

I am a final year PhD student at the University of Melbourne specialising in efficient large-scale cosmological simulations of the epoch of reionisation.
