Simulations of black hole accretion and jets

As black holes accrete surrounding gas, they often produce relativistic, collimated outflows, or jets. Jets form in the vicinity of a black hole and can be powerful probes of strong-field gravity. Jets inject energy and momentum into their environment and can affect galaxy evolution. However, how the properties of a jet connect to those of the accretion flow and the black hole (e.g. black hole spin) remains an area of active research. I will discuss recent progress in first-principles general relativistic magnetohydrodynamic (GRMHD) models of black hole accretion-jet systems, specifically the emerging picture of how jets form and the factors that determine jet properties.

The National Radio Astronomy Observatory and Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
