    Fermi Institute, Argonne researcher Hays to present 65th Compton lecture series on powerful gamma rays

    A series of lectures at the University will explore how black holes, remnants of exploded stars and other exotic celestial objects emit streams of powerful gamma rays.

    “The Quest for Gamma Rays: Exploring the Most Violent Places in the Universe,” is the title of this year’s Arthur Holly Compton Lecture series, sponsored each spring and fall by the University’s Enrico Fermi Institute. The 65th series of these public lectures will be held from 11 a.m. to noon each Saturday through June 2 (except for April 21 and May 26, when there will be no lectures). The lectures will be given in Room 106 of the Kersten Physics Teaching Center, 5720 S. Ellis Ave.

    Delivering the lectures this spring will be Elizabeth Hays, Research Associate in the Enrico Fermi Institute and at Argonne National Laboratory. Hays received her B.A. in physics from Cornell University in 1999 and her Ph.D. in physics from the University of Maryland in 2004.

    Among the topics she will discuss is the work of VERITAS (Very Energetic Radiation Imaging Telescope Array System). An array of four telescopes at Kitt Peak in southern Arizona, VERITAS is one of the most sensitive high-energy gamma-ray observatories in the world.

    Intended to make science accessible to a general audience and to convey the excitement of new discoveries in the physical sciences, the Compton lectures are named for Arthur Holly Compton, a former physicist at the University. Compton is best known for demonstrating that light has the characteristics of both a wave and a particle. He organized the effort to produce plutonium for the atomic bomb and directed the Metallurgical Laboratory at Chicago, where Enrico Fermi and his colleagues produced the first controlled, nuclear chain reaction in 1942.
