A new study has found the first ten confirmed intermediate-mass black hole active galactic nuclei (defined as black holes having between about 100 - 300,000 solar-masses). NASA/ Spitzer/IRAC WebActive galactic nuclei (AGNs) are perhaps the most violently energetic objects in the universe. AGNs are located at the centers of some galaxies — perhaps most galaxies — and emit a tremendous amount of energy, sometimes on the order of trillion times the output of the Sun. An AGN may outshine all the stars in its galaxy by a factor of 100. circle k texas pecan coffee
