Imaging Black Holes with the Event Horizon Telescopes

 

Abstract

In April the Event Horizon Telescope Collaboration released the first image of a black hole in which the ring predicted by general relativity is clearly visible.  The EHT is a millimeter-wavelength interferometric array used to image this source, M87, as well as other supermassive black holes and active galactic nuclei.  From its humble beginnings as an ad hoc array of a few existing millimeter observatories retrofitted to serve as a non-imaging very long baseline interferometer, the EHT has progressed to become a global imaging array.  This presentation will cover the main scientific results of the EHT as well as its technological history and possible future.

 

 

 

 

 

Connect with NRAO

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

Founded in 1956, the NSF NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NSF NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NSF 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. NSF NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The U.S. National Science Foundation (U.S. 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.
