LIGO confirms RIT's breakthrough prediction of gravitational waves

12.02.2016

RIT's 2005 landmark research matches the actual waveform signals

Research conducted by Rochester Institute of Technology scientists was integral to the breakthrough detection of gravitational waves from binary black holes that was announced today by the Laser Interferometer Gravitational-wave Observatory (LIGO) Scientific Collaboration.

The collaboration's findings confirm the existence of gravitational waves predicted by Albert Einstein's 1915 general theory of relativity and introduce a revolutionary new way of understanding the universe through gravitational wave astronomy. Six Rochester Institute of Technology researchers are among the authors on the upcoming paper in Physical Review Letters.

The LIGO paper prominently cites 2005 landmark research on binary black hole mergers led by Manuela Campanelli, director of RIT's Center for Computational Relativity and Gravitation. The signal detected by LIGO matches the numerical model of the waveform confirmed by RIT researchers and predicted in their 2005 breakthrough science, "Accurate Evolutions of Orbiting Black-Hole Binaries without Excision," originally published in Physical Review Letters, on March 22, 2006. The paper recently appeared in the American Physical Society's curated collection of seminal papers celebrating 100 years of Einstein's theory of general relativity.

Based on this milestone work from a decade ago, RIT researchers at the center, Carlos Lousto and James Healy, numerically modeled the merger of a pair of black holes and simulated gravitational waveforms. The actual wave patterns LIGO detected on Sept. 14, 2015, matched the simulations Lousto and Healy had created.

"The direct observation of a binary black hole merger by LIGO is an amazing confirmation of our theoretical calculations," said Campanelli, professor in RIT's School of Mathematical Sciences and an American Physical Society Fellow. "This is a historic moment in science."

The RIT team's breakthrough, known as the "moving puncture" approach, solved the interrelated equations for strong field gravity that comprise Einstein's theory of general relativity. Their method radically transformed the landscape of numerical relativity--a specialized field that solves Einstein's equations with sophisticated mathematics and supercomputers--and opened frontiers in gravitational wave astrophysics, Campanelli said.

RIT scientists used the moving puncture approach to make the first calculations of gravitational radiation from merging black holes with arbitrary masses and spins, and the discovery of large gravitational-radiation recoils from spinning supermassive black-hole mergers. The method also made possible their study of spin dynamics effects, such as spin-flips, precession and hang-up orbits, and extreme mass-ratio binaries.

"It is incredibly exciting to see the deep connections between theory and observation," said Lousto, a co-author on both the 2006 and LIGO breakthrough papers. "This is the Holy Grail of science. To confirm amazing predictions of general relativity is a dream come true. We have witnessed a historic event, the confirmation of the 100-year-old predictions of Einstein regarding gravitational waves and our 10-year-old computation of the merger of two black holes in a single event."

Collaborator Pedro Marronetti, program director of the division of gravitational physics at the National Science Foundation, noted that the simplicity and accuracy of their moving-puncture technique "opened up the field to a number of groups, large and small, all across the world."

RIT associate professor Yosef Zlochower, then a postdoctoral fellow and the fourth member of Campanelli's team, said, "We are witnessing the dawn of a new understanding of the universe," he said. "This has been decades in the making, and we are very proud to be part of this great effort."

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
