Thomas Korff Gaisser (March 12, 1940, Evansville, Indiana – February 20, 2022, Swarthmore, Pennsylvania)[1] was a particle physicist, cosmic ray researcher, and a pioneer of astroparticle physics.
In England the two studied at different universities, but their romance deepened when Gaisser wrote to her asking if she would like to see some plays in London during the academic holidays.
[7] From 1967 to 1969, Gaisser was a research associate at Massachusetts Institute of Technology (MIT) and, for the academic year 1969–1970, a NATO postdoctoral fellow at England's University of Cambridge.
He gained an international reputation for his research in modeling complex phenomena in analytic or semi-analytic formulations involving cosmic-ray physics.
He is one of the creators of the Monte Carlo event generator called "Sibyll",[6] which is an important simulator for air showers caused by cosmic rays.
[6] In 1985, Gaisser and his Bartol colleague Todor Stanev calculated the flux of atmospheric neutrinos from Cygnus X-3, a binary star system.
[6] He was one of the founding editors of the journal Astroparticle Physics (first published in 1992) and served as a member of the Franklin Institute Committee on Science and the Arts.
He is the author of the book Cosmic Rays and Particle Physics (1990); the 2nd edition (2016) was co-authored by Ralph Engel and Elisa Resconi.
