SQuIGGLE

The Survey

Catching massive galaxies just after they quench.

SQuIGGLE targets massive post-starburst galaxies at intermediate redshift. As the unpolluted byproducts of the rapid quenching process, these post-starburst galaxies offer a direct window into the physics that drives the formation of the most massive galaxies in the Universe.

We are assembling a multi-wavelength portrait of this rare transitional population: recent star formation histories and rates (SDSS · DESI · Keck · Magellan · Gemini), structures (HST · Subaru/HSC), cold gas and dust (ALMA), AGN properties (VLA · SDSS · WISE), and, most recently, dust-obscured star formation (JWST/NIRSpec IFU).
