Work
X-ray astronomy reveals hot plasma, compact objects, and energetic processes invisible to optical telescopes.
Trumper led ROSAT, an all-sky X-ray mission that detected hundreds of thousands of galactic and extragalactic sources.
ROSAT transformed X-ray source catalogs and expanded the observational basis for compact-object astrophysics.
