Unveiling the Primary Quenching Mechanisms in Galaxies through Large Spectroscopic Surveys
… Digital Sky Survey, we have investigated how galaxy quenching depends on both the internal properties of galaxies (i.e. stellar mass) and external factors (i.e. environment), how galaxy quenching has evolved across cosmic time and how quenching operates within galaxies. Building upon an …

Constraining the Quenching Mechanisms in Galaxies
… galactic outflows, and the heating of the galaxy halo and subsequent halting of gas accretion caused by virial shocks and preventative AGN feedback. Nonetheless, we still lack a clear understanding of which mechanism is the most important for quenching galaxies. The goal of this thesis is …

Quenching mechanisms in recently quenched elliptical galaxies: insights from neutral hydrogen studies and environmental analysis
… galaxies. However, the mechanisms driving their quenching remain elusive. We conduct a multi-wavelength analysis of 695 RQEs, along with their precursors (preRQEs) and descendants (postRQEs), focusing on their neutral hydrogen (HI) content and star formation properties. Contrary to conventional …

Regulating and Quenching Star Formation in Galaxies across the Cosmic Epochs
… thesis uncovers the mechanisms regulating and quenching star formation in galaxies from cosmic dawn to the present. Based on optical spectroscopy of 10,000 local galaxies from the MaNGA survey, I report the discovery of a stellar Fundamental Metallicity Relation, a smooth relation between …

Quenching of Star Formation in the Local Universe A Comparison of Hydrodynamical Simulations with Spectroscopic Observations
… physical processes responsible for ceasing, or ‘quenching’, star formation in galaxies is one of the most important unsolved questions in the field of galaxy evolution. Over the past two decades multiple mechanisms were suggested as potential drivers of the transition between the star-forming and …

New Insights on the Evolutionary Mechanisms of Local and Distant Galaxies
… stopping of star-formation is the process of galaxy quenching. Exploring this is the target of my thesis. In the first part of my thesis I use a methodology of partial correlation coefficients and random forest regression to disentangle multiple inter-correlated galaxy properties enabling me …
