He and a number of colleagues theorize that energy streaming from hot gas around a supermassive black hole could compress, stir, and irradiate the surrounding environment in a way that helps regulate the growth of the galaxy and the production of stars.

They form when stars collapse, leaving behind a black hole with dense mass that exerts gravitational force on the objects around it.

«We know that these showers are linked to the jets because they're found in filaments and tendrils that wrap around the jets or hug the edges of giant bubbles that the jets have inflated,» said Tremblay, «And they end up making a swirling «puddle» of star - forming gas around the central black hole.»

Synchronous orbits exist around all moons, planets, stars and black holes — unless they rotate so slowly that the orbit would be outside their Hill sphere.

Based on data taken by NASA's Chandra X-ray Observatory, the model takes into account how energy flows between two regions around the black hole — an inner core close to the boundary beyond which light can not escape (the event horizon) and an outer ring that extends far out and includes the massive young stars lurking near the black hole.
