Astronomers witness supermassive black hole gorge on a cosmic meal before 'burping' radio jets 300 days later

Using the NASA X-ray spacecraft Swift combined with radio observations, astronomers have observed a supermassive black hole burping radio jets 300 days after a heavy cosmic meal. The team was also able to roughly estimate the mass of this feeding cosmic titan, which sits at the heart of the Perseus Cluster, a massive collection of thousands of galaxies.

The black hole sits at the center of the galaxy NGC 1275, located around 225 light-years away, and is the brightest galaxy of the Perseus Cluster. The supermassive black hole first flared in X-rays, which indicated an increase in the rate at which it was accreting matter. Actively feeding supermassive black holes sit in regions called active galactic nuclei (AGNs), with their immense gravity heating surrounding matter, causing them to glow brightly. These emissions are boosted by material channeled to the poles of the central black hole, from where it is blasted out as powerful twin jets that shine across ...
