Livermore scientists assist in solving riddle of black hole spin
Wednesday, February 27, 2013 - 5:00pm
Using equipment that expands on technology funded by NNSA's Laboratory Directed Research and Development program, an international team has achieved the first successful measurement of the spin rate of a supermassive black hole. The team included scientists from Lawrence Livermore National Laboratory. In addition, Livermore’s High Energy Focusing Telescope served as the predecessor to NASA's Nuclear Spectroscopic Telescope Array, which was used to complete the study. The findings are significant because they enhance scientists' understanding of how black holes and galaxies evolve.
