SUMMARY: Sometimes the supermassive black holes at the hearts of galaxies are quiet, and nearly invisible. Other times they're actively gobbling up material, blazing as quasars in the X-ray spectrum. NASA's Chandra X-Ray Observatory has observed one of these transition times, when the heated material around the supermassive black hole is beginning to ignite. It's likely the galaxy recently collided or merged with another galaxy, and the turbulence caused material to fall into the black hole.

The whole business of SMBHs in the centers of galaxies beaming energy out and being quasars is very interesting. Identifying recently restarted quasars for later examination by higher resolution equipment, such as SKA seems like a very good thing. I wonder how rapidly this quasar's image will change.
