Biography
Professor Tomozawa's studies include theoretical and experimental work on the solar neutrino problem (the depletion of solar neutrino flux). His work on the enhancement of neutrino cross-sections by magnetoplasma properties attempts to explain observed anticorrelation of the solar neutrino flux and solar activity in recent experiments. Professor Tomozawa is also exploring the possibility of an efficient neutrino detector and a control of radioactivity.

By choosing the metric in general relativity as the exact solution to the Einstein equation that …ts the time delay data, one can determine the gravitational redshift on the surface of neutron stars. The author presents the physical metric that …ts observed time delay data and using the Kerr metric, the author has shown the e¤ect of a pulsar’s rotation on gravitational redshift in the determination of gravitational wave frequency is within 1 %. Based on this result, the author has identi…ed potential pulsar candidates with gravitational wave spectra that will be critical in the study of gravitational redshift and the relationship between rotation and gravitational waves of a neutron star.
