16. Physics-informed inferences of galaxy clustering with Bayesian forward modelling
Abstract : In this thesis, we showcase four novel approaches to constraining the relationship between cosmological observables and the large-scale structure. The majority of the energy content of the Universe in the concordance cosmological model remains largely unknown. READ MORE

17. A study of galaxy evolution: stacking emission lines from distant galaxies
Abstract : To draw up a thorough description of galaxy evolution exhaustive observations are needed, of distant but mainly of faint galaxies. Describing low mass galaxies is important to move the focus from the tip of the iceberg. READ MORE

18. The galactic scale impact of feedback from individual stars
Abstract : Feedback from stars is essential for the formation and evolution of galaxies. It is an energy source that drives gas motions and chemically enriches the galaxy by supplying metals. Without this stellar feedback, numerical galaxy simulations result in galaxies with little resemblance to those observed in our Universe. READ MORE

19. Galaxies in the epoch of reionization : Investigating the high-redshift galaxy population through simulations and observations
Abstract : The cosmic reionization is the last major gas phase transition in cosmic history, yet it remains poorly understood. Current constraints indicate that early star-forming galaxies drove the reionization process through producing and releasing large numbers of ionizing photons into the intergalactic medium. READ MORE

20. Using Lyα to illuminate the circumgalactic medium and the Epoch of Reionization : Lessons from low redshift
Abstract : The field of extragalactic astronomy is progressing rapidly but there is still much to understand and many questions that remain open. During recent years the Lyα emission line has come to the fore as a potentially very powerful astrophysical tool and is now routinely used to find galaxies at the very highest redshifts. READ MORE
