I am a second year PhD student supervised by Dr Francesco D'Eugenio and Prof Sandro Tacchella. I am willing to contribute to uncovering the puzzling mysteries surrounding the processes that governed Galaxy Formation and the subsequent structural growth and morphological evolution within the first billion of years after Big Bang.

My first project represents a detailed study of the kinematics and dynamics of a Massive Quiescent Galaxy at redshift z = 4.66 (GS-9209). The galaxy shows an ordered rotation pattern and a young central bulge. Detailed dynamical modelling reveals that this massive galaxy has a surprisingly low dark matter content compared to numerical simulations. The project has been finished and accepted for publication into the Monthly Notices of the Royal Astronomical Society (MNRAS) and is available at the following link

My second project aims to probe study the interstellar medium and to unveil the nature of the brightest galaxy at a redshift z > 10. The target is made of two prominent clumps, with substantially different stellar masses and gas-phase metallicities. Between the two clumps, we find highly-turbulent and metal-poor gas, which triggers a significant increase in the recent star formation in the region.
