Coauthored the Kamiokande observation of the SN 1987A neutrino burst. The discovery paper reported eleven electron events over thirteen seconds, with reconstructed energies from to ; their clustering in time supplied evidence for a short neutrino signal from the supernova.[ref]

A researcher whose team developed a radiochemical search for solar neutrinos. Their 1968 report with Raymond Davis Jr. and Don S. Harmer converted a limit on argon production in a chlorine detector into a bound on the incoming neutrino flux. The measurement illustrates how a detector’s target nuclei and reaction cross section connect a rare nuclear event with an astronomical inference.[ref]
Search for Neutrinos from the Sun by Raymond Davis Jr. and others. Abstract: capture-rate upper limit, cross sections and inferred solar flux
An experimental researcher whose joint work with Raymond Davis Jr. and Kenneth C. Hoffman used a nuclear conversion to search for solar neutrinos. A neutrino captured by chlorine can produce radioactive argon. Detecting that product provides an indirect way to measure an extremely weakly interacting particle flux, allowing observations on Earth to constrain nuclear processes inside the Sun.[ref]

An experimental researcher whose team observed Bose-Einstein condensation in sodium gas in 1995. A trap combining magnetic and optical forces allowed evaporative cooling to greatly increase the cloud’s phase-space density. Images after release developed two distinct components: a broad thermal cloud and a dense, elliptically expanding core. Their appearance made the transition measurable and provided an experimental system for studying the collective behavior of a dilute quantum gas.[ref]

An experimental researcher whose team produced a Bose-Einstein condensate in dilute rubidium vapor in 1995. Magnetic trapping of neutral atoms confined the cloud, while evaporative cooling removed energetic atoms. The decisive evidence was a narrow, anisotropically expanding component appearing within a broader thermal velocity distribution. Its sudden growth as the cloud cooled connected the observed images with macroscopic occupation of the trap’s lowest quantum state.[ref]
