    • Aeons Before the Big Bang? 

      Penrose, Roger (Georgia Institute of Technology, 2009-03-24)
      There is much impressive observational evidence, mainly from the cosmic microwave background (CMB), for an enormously hot and dense early stage of the universe referred to as the Big Bang. Observations of the CMB are now ...
    • The Astrophysics of Black Hole Spin 

      Reynolds , Chris (Georgia Institute of Technology, 2013-04-22)
      In addition to providing vital clues as to the formation and evolution of black holes, the spin of black holes may be an important energy source in the Universe. Over the past couple of years, tremendous progress has been ...
    • The Astrophysics of Supermassive Black Holes 

      Ballantyne, David (Georgia Institute of Technology, 2014-10-21)
      Black holes are perhaps the most mysterious and enigmatic objects that one can imagine. Their gravitational fields are so strong that light is unable to escape their grasp, and even fundamental quantities such as space ...
    • Bowen-type initial data for simulations of neutron stars in binary systems 

      Clark, Michael C. (Georgia Institute of Technology, 2016-04-12)
      A new method for generating initial data for simulations of neutron stars in binary systems. The construction of physically relevant initial data is crucial to accurate assessment of gravitational wave signals relative to ...
    • Cosmic Information Theory and Analysis: IT from BIT, from BITs in IT 

      Bond, J. Richard (Georgia Institute of Technology, 2011-11-30)
      We consider the Universe to be fundamentally quantum and statistical, the many-paths/many-worlds story. This lecture uses Cosmic Information Theory and Analysis, CITA, as a unifying theme to explore the vast sweep of our ...
    • Cosmic Rays: Alien Invaders from Outer Space 

      Otte, Nepomuk (Georgia Institute of Technology, 2013-12-02)
      Cosmic rays are microscopic, charged particles that permanently bombard Earth from outer space. 100 years after their discovery their origin is still a mystery. It is also not clear how cosmic rays can obtain energies that ...
    • Dark Chocolate: Dark Matter or Dark Energy 

      Ludovice, Peter J.; Hunt, William D.; Oluseyi, Hakeem (Georgia Institute of Technology, 2009-06-03)
      Join our guest Hakeem Oluseyi from the Department of Physics and Space Science at the Florida Institute of Technology in discussing cosmology from dark matter to dark energy and the importance of diversity in physics. ...
    • Gravity's Strongest Grip: A Computational Challenge 

      Shoemaker, Deirdre (Georgia Institute of Technology, 2010-10-22)
      Gravitational physics is entering a new era driven by observation that will begin once gravitational-wave interferometers make their first detections. In the universe, gravitational waves are produced during violent events ...
    • Hot Research from the Coldest Place on Earth 

      Ludovice, Peter J.; Zangwill, Andy; Taboada, Ignacio (Georgia Institute of Technology, 2009-04-15)
      Ignacio Taboada from the School of Physics joins Pete and his special guest host Andy Zangwill to discuss Astrophysics at the South Pole. Using a cubic kilometer of ice, Prof. Taboada traps neutrinos in order to map activity ...
    • It's All Relative 

      Ludovice, Peter J.; Hunt, William D.; Laguna, Pablo; Wathen, Adam (Georgia Institute of Technology, 2009-12-16)
      Pablo Laguna from the Georgia Tech School of Physics will join us to talk about General Relativity, Gravity and what happens when Black Holes collide. Georgia Tech Graduate Student Adam Wathen will also be on hand to ...
    • Observation of Astrophysical Neutrinos by IceCube 

      Taboada, Ignacio (Georgia Institute of Technology, 2013-09-16)
      Even though cosmic rays were discovered more than 100 years ago, their origin remains a mystery. Neutrinos, product of cosmic ray interactions at or near the production site, are the best astrophysical messenger to find ...
    • Physical tests for timeloops 

      Massopust, Peter Robert (Georgia Institute of Technology, 1981-05)
    • Post-Shuttle Age: The Future of NASA 

      Ballantyne, David; Korzun, Ashley; Krige, John; Spencer, David (Georgia Institute of Technology, 2011-03-31)
      Panelists David Ballantyne, Assistant Professor in the School of Physics and the Center for Relativistic Astrophysics (CRA); Ashley Korzun, graduate student in the Daniel Guggenheim School of Aerospace Engineering; John ...
    • Scaler System Testing in the HAWC Experiment 

      Browning, Tyler (Georgia Institute of Technology, 2010-05-12)
      TeV gamma rays probe the non-thermal Universe in ways that are not possible at other wavelengths. The HAWC observatory, under construction in Mexico, will be able to analyze and survey the TeV sky more completely than any ...
    • Search for high energy GRB neutrinos in IceCube 

      Casey, James David (Georgia Institute of Technology, 2015-05-14)
      The IceCube Neutrino Observatory has reported the observation of 35 neutrino events above 30 TeV with evidence for an astrophysical neutrino flux using data collected from May 2010 to May 2013. These events provide the ...
    • Search for neutrino transients using IceCube and DeepCore 

      Daughhetee, Jacob D. (Georgia Institute of Technology, 2015-03-31)
      Observations indicate that there is a correlation between long duration gamma-ray bursts (GRBs) and core-collapse supernovae (SNe). The leading model for GRB production assumes that relativistic jets are generated by the ...
