Will the Real Monster Black Hole Please Stand Up?

[attachment=0]pia18907-16.jpg[/attachment]Tale of Two Black Holes
A new high-energy X-ray image from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has pinpointed the true monster of a galactic mashup. The image shows two colliding galaxies, collectively called Arp 299, located 134 million light-years away. Each of the galaxies has a supermassive black hole at its heart.

NuSTAR has revealed that the black hole located at the right of the pair is actively gorging on gas, while its partner is either dormant or hidden under gas and dust.

The findings are helping researchers understand how the merging of galaxies can trigger black holes to start feeding, an important step in the evolution of galaxies. ...

The real monster black hole is revealed in this image from NASA's Nuclear <br />Spectroscopic Telescope Array of colliding galaxies Arp 299. In the center <br />panel, the NuSTAR high-energy X-ray data appear in various colors overlaid <br />on a visible-light image from NASA's Hubble Space Telescope. The panel on <br />the left shows the NuSTAR data alone, while the visible-light image is on the <br />far right. Image Credit: NASA/JPL-Caltech/GSFC
