Guest Speaker: Jessie Thwaites, Ph.D. candidate – University of Wisconsin-Madison
Summary: Along with being a Ph.D. student, Jessie works at the IceCube Neutrino Observatory located in Antarctica. In this talk, Jessie explains how by using different astrophysical messengers, astronomers can garner information about the universe. There are four main astrophysical messengers: photons, cosmic rays, neutrinos, and gravitational waves. Neutrinos are chargeless, massless particles that emanate from neutron particle decay. The IceCube Neutrino Observatory captures the “light boom” the neutrino produces as it interacts with the ice. With these detectors, astronomers can inform other astronomers that a transient astronomical event is happening in real-time.
This is a fascinating opportunity to learn how physicists and astronomers use astrophysical messengers to probe the universe. We hope you enjoy it!
