Summary
Galaxies form, grow and evolve by exchanging gas with their environment. Information about gas flows in and out of galaxies is encoded in their circumgalactic medium (CGM). Studying the CGM is therefore crucial to understand galaxy formation and evolution. However the detection of the CGM is challenging because of its low density. Historically, the CGM has been detected using absorption lines techniques providing only local information about the gas distribution and limited to rare cases where a bright source is in the background. Until very recently, the 2D mapping of the CGM was only possible for rare and massive nearby galaxies or required the use of, often criticized, stacking methods. The arrival of 3D spectrographs have revolutionized the study of the CGM by enabling the detection of low surface brightness diffuse gas. By leveraging the exquisite MUSE deep fields data, the C3UBES project aims at providing a comprehensive 3D-mapping of the CGM for an unprecedented statistical sample of distant galaxies. By exploiting the complementarity between absorption and emission line studies in the MUSE deep cubes as well as the magnification power of gravitational lensing, my project will shed light on the CGM gas content, its morphology and the gas kinematics around galaxies. Connecting the CGM to the host galaxy properties will help us understand how the CGM regulates galaxy growth. The unprecedented C3UBES sample will allow me to statistically study the evolution of this relationship over almost half the history of the universe. The excellence of the research environment at CRAL (host institute) and the expertise of my supervisor will give me the best opportunities to enhance and expand my career possibilities. Finally, coming back to Europe and increasing my national and European visibility thanks to the MSCA fellowship appear like the next logical steps to pursue my career.
