A wispy collection of atoms and molecules fuels the vast cosmic maelstroms produced by colliding galaxies and merging supermassive black holes, according to some of the most advanced supercomputer simulations ever conducted on this topic.
“We found that gas is essential in driving the co-evolution of galaxies and supermassive black holes,” said Stelios Kazantzidis, a Fellow in the University of Chicago’s Kavli Institute for Cosmological Physics. He and his collaborators published their in February on astro-ph, an online repository of astronomical research papers. They also are preparing another study.
The collaboration includes Lucio Mayer from the Swiss Federal Institute of Technology, Zurich, Zwitzerland; Monica Colpi, University Milano-Bicocca, Italy; Piero Madau, University of California, Santa Cruz; Thomas Quinn, University of Washington; and James Wadsley, McMaster University, Canada. “This type of work became possible only recently thanks to the increased power of supercomputers,” Mayer said. Improvements in the development of computer code that describes the relevant physics also helped, he said.
“The combination of both code and hardware improvement makes it possible to simulate in a few months time what had required several years of computation time only four to five years ago.” READ MORE
