    A free public lecture by NYC Astrophysicist Gabriel Perez-Giz.   What are black holes?  What makes them so amazing?

    In 2010, Professor Perez-Gil won a National Science Foundation Astronomy and Astrophysics Postdoctoral Fellowship to carry out a program of research and education at the Massachusetts Institute of Technology (MIT) Kavli Institute for Astrophysics and Space Research (MKI) on the study of orbital motions of Black Holes.

    In the abstract for the award, the NSF stated, "The dynamics of black hole (BH) binaries is especially dynamically rich since the nonlinear footprint of general relativity (GR) will be most visible in the regime of large masses and small separations achievable by such massive compact objects. Unlike in classical celestial mechanics, the motion in such ultra-relativistic binaries is complicated by the loss of energy and angular momentum to gravitational waves (GWs), which causes the orbiting bodies to spiral inward and eventually merge. Unfortunately, systematic numerical study of inspiraling black hole binaries is not possible in the status quo with either numerical relativity (too computationally expensive) or Post-Newtonian approximations (too inaccurate).

    ....However, when the ratio of the masses is extremely small, as when a stellar-mass BH orbits a supermassive galactic BH, the inspiral calculation becomes tractable....

    ....Dr. Perez-Giz will adapt this code to achieve a many-fold improvement in computational efficiency via a technique exploiting special properties of periodic geodesics around Kerr black holes...."

    Please join us on Friday night at the Kaufman Auditorium at the American Museum of Natural History as NYU Physics Professor Gabriel Perez-Gil explains the current state of the art of our understanding of Black Holes - - in everyday language.
