J03.00001: The Pre-History of the Two Black Hole Collision Problem Invited Speaker: Larry Smarr From the first mathematical solution of Einstein’s equations of General Relativity, representing what we now know as a black hole, in 1918 to the observation of the gravitational radiation from two colliding black holes in 2015 was almost 100 years. I will give a brief history of the mathematical and computational developments, up to the 1970s when the first computational solution of Einstein’s equations for two black holes colliding head-on was obtained. The 1920s saw the equation of motion posed, the 1930s envisioned the two-body problem, the 1940s set up the Cauchy problem, the 1950s conceived of numerical relativity, the 1960s witnessed the first numerical solutions, and the 1970s produced the first numerical collision with generation of gravitational radiation.

J03.00002: Numerical Relativity 1980-2000s: The era of sharpening our tools and exploring Einstein's physics Invited Speaker: Ed Seidel I will review progress made in numerical relativity during the quarter-century from 1980 - 2005 when the tools and techniques of solving the most complex PDEs in mathematical physics---Einstein's equations---developed and matured, taking the field from early proof-of-concept and heroic breakthroughs to essential approaches for exploring general relativity and relativistic astrophysics. Our current ability to solve these equations routinely represents one of the most impressive achievements in all of computational science. ~I will review key advances in techniques, hardware and software capabilities, and community development, along with important scientific breakthroughs enabled by them. Particularly important developments that helped build both the community and its capabilities include the NSF Black Hole Grand Challenge in the US, the creation of the Albert Einstein Institute in Germany, and the EU Astrophysics Network across Europe. At the same time, the LIGO-VIRGO-GEO detector projects provided important guide stars for this developing field. Collectively, these projects laid the foundation for a community ready to enter the era of multi-messenger astronomy. [Preview Abstract] |

J03.00003: Binary Black Hole Mergers: Breakthroughs, Waveforms, Astrophysics, and Gravitational Waves Invited Speaker: Joan Centrella In 2005, three numerical relativity groups achieved breakthroughs that enabled the first fully three-dimensional calculations of merging binary black holes and the resulting gravitational waveforms. This talk will begin with an overview of these achievements, setting them within the context of the numerical and theoretical challenges at the time. We will then discuss how these achievements truly did "break open" the field of numerical relativity, enabling the solution of increasingly more challenging problems, surprising discoveries, and key astrophysical applications. We will conclude with a look at the role of numerical relativity simulations in the experimental discovery of gravitational waves from merging binary black holes. [Preview Abstract] |
