Significant scientific endeavors

Supernova modeling

Demonstrated the production of high speed jets by the collapse of a magnetized rotating star.

Developed a spherical model for the collapse of massive stars to produce supernova explosions.

Discovered the late time neutrino heating mechanism that produced suicient energy in the supernova explosion.

Gave the output of the supernova calculations to several people with nuclear burn codes to produce r-process nuclei.

Devised a model to explain the supernova remnants observed very close to the galactic black hole. This model arises from the compression of a white dwarf star by general relativistic effects.

Numerical Relativity

Wrote a sperically symmetric general relativistic program that solved the hydrodynamic equations as well as the Boltzmann equation for the neutrinos.

Studied magnetized black holes and showed the extraction of rotational energy and also the possibility of the occurance of highly electrically charged black holes.

Developed a computer model for an inhomogeneous cosmology that only varies in one spatial direction.

Developed a computer model for calculating the structure of close neutron star binaries. The model showed compression of stars as they came close and yielded black hole formation before the final merger.

Nuclear physics

Modeled heavy-ion nuclear collisions and used data to make a high density nuclear equation of state.

Current projects

Make a better supernova model for r-process calculations. Include off-diagonal neutrino oscillations in the supernova model. Attempt to model the "dark energy" induced expansion of universe by the decay of sterile neutrinos.

Developing an inhomogeneous cosmological computer model that includes the decay of neutrinos.
