About

Thomas de Jaeger is an astrophysicist whose research centers on the observational study of supernovae (SNe) and their host galaxies, with a particular focus on the earliest phases of stellar explosions. His major contributions include leading the "Snapshot Survey of Nearby Supernovae with the Hubble Space Telescope," a pioneering program that captures high-resolution ultraviolet and optical imaging of SNe discovered by robotic surveys. This work has been instrumental in characterizing the progenitor systems and explosion environments of nearby events, often catching them before peak brightness—a critical window for understanding their physics. With over 9 citations for this flagship study alone, de Jaeger’s research has deepened our grasp of core-collapse and thermonuclear supernovae, linking observational data to theoretical models. His efforts have also advanced the use of SNe as cosmological distance indicators, refining measurements of the universe’s expansion. A rising figure in time-domain astronomy, de Jaeger’s work exemplifies how targeted Hubble follow-up can unlock the secrets of transient phenomena, making him a key voice in the next generation of supernova science.
