Hi Everyone,</div>

Our seminar this Wednesday will be given by Dr. Renske Smit (LJMU). Our seminar will be in C4 followed by wine and cheese. The abstract and title are provided below. </div>

<span style="font-family: "Helvetica Neue"; font-size: 13px; color: black;">The study of galaxy formation in the first billion years of cosmic time (z>6) has recently seen a transformation due to the long-awaited data from the JWST. Galaxies that were first
glimpsed by Hubble, now have measurements of star-formation, metal build-up and ionisation properties from emission lines emerging in hot, ionised gas. The physical processes underlying early star and galaxy formation, however, require understanding of the
cold gas and dust in these systems, which can now be studied by combining state of the art data from ALMA and the JWST. In this talk I will focus on the latest results to understand the build-up of the first dust reservoirs in galaxies, the distribution of
cold gas and dust and the dynamical state of the cold gas in these galaxies. I will show new results on the detection of the 2175A ‘UV bump’ at z>6, that arises due to the presence of small carbonaceous dust grains (such as PAHs) and the constraints that we
derive for the formation and growth of dust in the early Universe. I will furthermore talk about the formation of the first disk galaxies in the first billion years of cosmic time and the turbulence of the cold gas that has the potential to regulate star-formation
activity in these early galaxies. </span></p>
