NGC 1277 is a compact little galaxy with one of the biggest black holes known to date. Its black hole weighs 17 billion times the mass of the Sun, which is an incredulously 14% of this galaxies total mass. Most of the stars in this galaxy are strongly affected by the gravitational pull of this black hole. And the black hole in this galaxy is bigger than our solar system. The research paper is published in Nature on November 29 2012.
The animation shows representative orbits of the stars in this galaxy from the dynamical model used to measure the black hole mass. The green orbit shows the orbit of the stars in the disk. The red orbit shows the strong gravitational pull near the black hole. The blue orbit is strongly influenced by the (round) dark matter halo. One second in this animation represents 22 million years of simulated time and the horizontal size of this image is 41 million lightyears (36 arcsec).
