Federico Armengol (Rochester Institute of Technology, Instituto Argentino de Radioastronomía) chats about his AAS Journal article on black hole binaries, and where we can go from here given the published article.
Article: "Circumbinary Disk Accretion into Spinning Black Hole Binaries"
Following-up articles mentioned in the video:
and a AAS NOVA highlight on the latter:
Federico's web presence:
The intended audience for the AAS Journal Author Series is active researchers.
This simulations shows the accretion patterns around two merging black holes. This is to show the smoothness of the transition between IllinoisGRMHD to harm3d, which are two different magnetohydrodynamics codes.
Manuela Campanelli, astrophysicist and Professor of Mathematical Sciences at Rochester Institute of Technology, simulates compact objects in the universe, like black holes and neutron stars. Frontera allows her team of researchers to simulate these complex systems twice as fast as previous systems.
Understanding the influence of distant stars: Manuela Campanelli, professor of astrophysics at Rochester Institute of Technology and director for the Center for Computational Relativity and Gravitation, is using Frontera to develop a simulation to amplify our understanding of gravitational waves. The goal is to explain the origin of the powerful energy bursts that are emitted during a neutron star merger, including the types of electromagnetic signals emitted. Frontera enables Campanelli and her team to perform complex simulations at a speed two or more times faster than what is possible on any local supercomputer.
Computer calculations modeling the gravitational waves LIGO has observed to date and the black holes that emitted the waves. The image shows the horizons of the black holes above the corresponding gravitational wave.
