Every year at the Annual Danish Astronomy Meeting (ADAM), the Instrument center for Danish Astrophysics (IDA) awards a prize for the most outstanding PhD thesis. This year's winner was John Weaver for his instrumental work on compiling a catalog of more than a million galaxies, observed with Hubble and other telescopes across the full electromagnetic spectrum.

The catalog is called "COSMOS2020", and with the data gathered through the seven years that has passed since the preceding data release, the catalog contains galaxies more than twice as faint as previously.

The power of COSMOS2020 lies in its use of bleeding-edge galaxy model-fitting techniques. With accurate measurements of the light emitted from radio waves, to infrared, and all the way to X-rays, the catalog not only shows a coherent history of the evolution of galaxies through 97% of time; it also provides a firm basis of follow-up observations with James Webb, in particular spectroscopy.

Congratulations, John!
