Title: Novel Probes of Dark Physics in the Late and Early Universe

Abstract: Over the last few years, astronomical observations are increasingly hinting at a discrepancy in our understanding of the Universe between late and early times. If this is due to new physics, non-standard dark matter or dark energy are prime candidates to explain the discrepancy. It is therefore interesting to develop novel observational probes of the late and early Universe that are sensitive to the properties of dark matter and dark energy. In recent and ongoing work, I have explored the novel use of voids in the late-time galaxy distribution, and the first generations of galaxies in the Universe, to test models of dark matter and dark energy with current and future astronomical data. I will present the main findings, and give an outlook for future prospects.
