Thomas W. Baumgarte is a Professor of Physics at Bowdoin College, and an Adjunct Professor of Physics at the University of Illinois at Urbana-Champaign. He received his Diploma (1993) and Doctorate (1995) from Ludwig-Maximilians-Universitat, Munchen, and held postdoctoral positions at Cornell University and the University of Illinois before joining the faculty at Bowdoin College. He is a recipient of a ... Read moreJohn Simon Guggenheim Memorial Foundation Fellowship. He has written over 65 research articles on a variety of topics in general relativity and relativistic astrophysics, including black holes and neutron stars, gravitational collapse, and more formal mathematical issues. Stuart L. Shapiro is a Professor of Physics and Astronomy at the University of Illinois at Urbana-Champaign. He received his A.B. from Harvard (1969) and his Ph.D. from Princeton (1973). He has published over 335 research articles spanning many topics in general relativity and theoretical astrophysics and co-authored the widely used textbook Black Holes, White Dwarfs and Neutron Stars; The Physics of Compact Objects (John Wiley, 1983). In addition to numerical relativity, Shapiro has worked on the physics and astrophysics of black holes and neutron stars, relativistic hydrodynamics, magnetohydrodynamics and stellar dynamics, and the generation of gravitational waves. He is a recipient of an IBM Supercomputing Award, a Forefronts of Large-Scale Computation Award, an Alfred P. Snow Research Fellowship, a John Simon Guggenheim Memorial Foundation Fellowship, and several teaching citations. He has served on the editorial boards of The Astrophysical Journal Letters and Classical and Quantum Gravity. He was elected Fellow of both the American Physical Society and Institute of Physics (UK). Show Less
