Astrophysics seminar

The first billion years after the big bang is both the time of the epoch of reionization and the early galaxy evolution. With the advances in telescope capabilities, not only are the number discovered galaxies at redshift z>6 increasing, but also the possibilities for understanding the physical properties of these galaxies. I will focus on zooming in on the interstellar medium of z>6 galaxies based on recent ALMA observations. With the combination of high sub-arcsec resolution and high sensitivity, ALMA is providing new, and in many cases unexpected, results about the gas and dust in early galaxies. Quantifying the physical properties of the ISM is key to understanding the interplay between early galaxy evolution and the ionization of the surrounding medium during the epoch of reionization. I will in particular focus on lensed galaxies, both studies of individual sources as well as stacking analysis based on the ALMA Lensing Cluster Survey.
