"We are seeing this object feast, burp, and nap, and then feast and burp once again, which theory had predicted," said Julie Comerford of the University of Colorado, who led the study, in a statement.

Astronomers Spot 'Flickering' Supermassive Black Hole
Dr. Julie Comerford from the University of Colorado at Boulder and colleagues used observations from NASAs Chandra X-ray Observatory and the NASA/ESA Hubble Space Telescope, as well as the W.M. Keck Observatory in Mauna Kea, Hawaii, and the Apache Point Observatory near Sunspot, New Mexico.
"Theory predicted that black holes should flicker on and off very quickly and this galaxy's evidence of black holes does flicker on timescales of 100,000 years - which is long in human timescales, but in cosmological timescales is very fast," said Julie Comerford.

Naked black hole has no stars, puzzling astronomers
In the case of SDSS J1126+2944, however, the two black holes within the galaxy still have yet to collide. According to investigator Julie Comerford, from the Colorado University, Boulder, One black hole is starved of stars, and 500 times fewer stars associated with it than the other black hole. The

In A Rare Galaxy With Two Black Holes, Neither Can Live While The Other Survives
One black hole is starved of stars, and has 500 times fewer stars associated with it than the other black hole, Julie Comerford, an assistant professor at the University of ColoradoBoulderand the lead investigator of the new research, said in a statement released Tuesday. The question is why th

Dueling black holes strange bedfellows in galaxy merger
Galaxies "merge all the time, but this phase where the two black holes are separated doesn't last that long," Julie Comerford, an assistant professor of astronomy at the University of Colorado at Boulder, told reporters at the American Astronomical Society's winter meeting in Kissimmee, Fla.
The rare pair -- one of only 12 known galaxies with two supermassive black holes -- likely are the result of two galaxies merging, astrophysicist Julie Comerford, with the University of Colorado, Boulder, said at the AAS conference.
