Center for Fundamental Theory Center for Theoretical and Observational Cosmology Center for Particle and Gravitational Astrophysics

The Institute for Gravitation and the Cosmos is a multidisciplinary institute of Penn State researchers dedicated to the study of the most fundamental structure and constituents of the Universe.

News and Events

  • Emily Rolfe Grosholz, Edwin Earle Sparks Professor and member of the Institute for Gravitation and the Cosmos, will offer a poetry reading on Thursday, January 30 at 7:30 PM in the Paterno Library's Foster Auditorium. Dr. Grosholz's most recent collections The Stars of Earth: New and Selected Poems(2017) and Great Circles: The Transits of Mathematics and Poetry (2018) "showcase her larger interests in the intersections between philosophy, mathematics, science and language."
  • Laser Interferometer Gravitational-wave Observatory’s LIGO) Livingston detector has made a lone discovery of what could possibly be a binary neutron star collision. This detection was made possible by the GSTLAL online software developed by faculty and postdocs at the Institute for Gravitation and the Cosmos. The total mass of the binary is significantly larger than all such systems we know in our galaxy and challenging astrophysical models of the formation of binary black holes. Full article
  • Penn State's Bianchi, Gupta and Sathyaprakash were coauthors of a paper that was awarded second prize of the annual Buchalter Cosmology prize announced at the AAS meeting in Hawaii in early January. The prize recognizes their work on the possible origin of LIGO's black holes in the very early Universe, offering quantum origin of their small spins. Full article
  • IGC’s Rachael Huxford was co-author of one of the most-read publications in The Physics Teacher of the American Association of Physics Teachers. The paper describes a demonstration on classroom simulation of gravitational waves from orbiting binaries. Popular demonstrations commonly use stretched spandex fabric to illustrate the way in which curved spacetime mimics the force of gravity in general relativity. In this spirt, Huxford and co-authors used a similar mode to illustrate gravitational waves from orbiting binaries, whose discovery was recognized with the 2017 Nobel Prize in Physics. They developed a simple and inexpensive demonstration which produces the pattern of outgoing spiral ripples that has entered the public imagination through images from numerical simulations.
