A few minor grammatical nits in your commentary. You used the word ‘quite’ when you likely intended to use the word ‘quiet’, and ‘massives’ instead of ‘masses’.

You can throw this comment into the black hole.

Hawkpilot: An active galactic nucleus (AGN) or blazar emits a lot of energy from its central supermassive black hole in wavelengths like X-rays and gamma rays. The supermassive black hole in a quiet galaxy like the Milky Way emits relatively little by comparison.
