Black Holes Lead Galaxy Growth

Posted on January 6, 2009April 5, 2017

Astronomers may have solved a cosmic chicken-and-egg problem — the question of which formed first in the early Universe — galaxies or the supermassive black holes seen at their cores.

Radio Telescopes Reveal Unseen Galactic Cannibalism

Posted on June 23, 2008April 5, 2017

Radio-telescope images have revealed previously-unseen galactic cannibalism — a triggering event that leads to feeding frenzies by gigantic black holes at the cores of galaxies.

Radio Telescopes Provide Key Clue on Black Hole Growth

Posted on January 9, 2007April 5, 2017

Astronomers have discovered the strongest evidence yet found indicating that matter is being ejected by a medium-sized black hole, providing valuable insight on a process that may have been key to the development of larger black holes in the early Universe.

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.
