Stars, black holes and galaxies

yousef 27/07/2024

Supermassive black holes are common in the centers of galaxies and may generate the most energetic phenomena in the known universe. It is believed that, around these black holes, matter falls in a rotating disk and part of this matter is expelled in opposite directions along two narrow beams, called jets, at speeds close to the speed of light, which typically produces a lot of radio emissions. Whether the radio emission we see from Sagittarius A* comes from the infalling gas or the outflowing jet is a matter of intense debate.
