The AGES Collaboration consists of four astronomers based in Arkansas working on issues relating to the mass  function of supermassive black holes in the Universe. AGES stands for Arkansas Galaxy Evolution Survey. The four  members are (in alphabetical order) Daniel Kennefick, Julia Kennefick and Claud Lacy, at the University of Arkansas,  Fayetteville, and Marc Seigar at the University of Arkansas, Little Rock. The group is working on several issues  relating to supermassive black holes, and the research behind the collaborations first publication is discussed here. One of the dramatic discoveries of astronomy in the late 20th century has been that apparently nearly all galaxies  have, at their center, a supermassive black hole, with a mass of between 10,000 and 1 billion times the mass of the  Sun. Such black holes, when they are swallowing material, are the source of the enormous outpouring of energy  characteristic of active galactic nuclei such as quasars. But in most galaxies there is a void around the central black  hole, where all the matter has already disappeared into the hole and so the black hole, starved of matter to devour, is quiescent. This makes the job of detecting these black holes very difficult, so that we know very little about the  typical size of the black holes in normal galaxies.
