Studying Quenching in Intermediate-z Galaxies: Gas, Angular Momentum, and Evolution
The SQuIGGLE Survey
Characterizing the physical mechanisms that "quench" massive galaxies, transforming them from blue star-forming disks into quiescent red ellipticals, is a hotly debated and poorly understood aspect of extragalactic astronomy. The SQuIGGLE survey targets massive post-starburst galaxies at z∼0.6, which are observed within a few hundred million years after they stopped forming stars. Our team has assembled a multi-wavelength view of their detailed physical properties including: ALMA CO(2-1) observations of molecular gas, Gemini/GMOS measurements of stellar kinematics, VLA and Keck/NIRES measurements of obscured star formation and AGN activity, and HST and Subaru/HSC imaging of stellar structures. Together we are building a picture of the detailed properties of these transitioning massive galaxies to unveil the physical processes that drive their transformation.
