Snyder coauthors the relativistic collapse model showing how a massive star can pass within its Schwarzschild radius
Oppenheimer analyzes continued gravitational collapse as an implication of general relativity
Publishes work with Snyder on continued gravitational contraction of massive stars.
Coauthors the relativistic model of gravitational collapse to a black-hole-like state.
With George Volkoff, shows that sufficiently massive neutron cores have no static equilibrium, helping establish the theoretical path toward gravitational collapse.
With Hartland Snyder, models continued stellar collapse and shows a sufficiently massive star can become cut off from communication with distant observers.
Finds neptunium during uranium irradiation studies.
Produces plutonium from uranium-derived neptunium.
Investigates electromagnetic methods for uranium separation.
The S-1 Executive Committee recommends a Tennessee pilot plant based on Lawrence's electromagnetic isotope-separation work.
Helps discover curium, later named for Pierre and Marie Curie.
Participates in the discovery of curium.
Helps identify curium among transuranium elements.
