VLBA Reveals Closest Pair of Supermassive Black Holes

Posted on May 17, 2006April 5, 2017

Astronomers using the National Science Foundation’s Very Long Baseline Array radio telescope have found the closest pair of supermassive black holes ever discovered in the Universe — a duo of monsters that together are more than 150 million times more massive than the Sun and closer together than the Earth and the bright star Vega.

Engine’s Running, But Where’s the Fuel?

Posted on January 11, 2006April 5, 2017

Astronomers have found a relatively tiny galaxy whose black-hole-powered central engine is pouring out energy at a rate equal to that of much larger galaxies, and they’re wondering how it manages to do so.

VLBA Observations Put New Twist on Quasar Jet Model

Posted on June 1, 2005April 4, 2017

When a pair of researchers aimed the National Science Foundation’s Very Long Baseline Array radio telescope toward a famous quasar, they sought evidence to support a popular theory for why the superfast jets of particles streaming from quasars are confined to narrow streams.

The National Radio Astronomy Observatory is a facility 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 U.S. 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.
