I am referring to this picture published here. Apparently super massive black holes emit radiation and matter in astrophysical jets. And these jets can form galaxies. I have some questions:
Isn't throwing out matter contrary to what a black hole is supposed to do? I imagine that the collapsing stars and gas falling into black hole would get super-heated and would emit energy as radiation but why would it throw out matter?
The matter is said to leave at near speed of light. Can such fast moving jet condense to form a galaxy? If it does, shouldn't it be a stretched, thin thread like structure and not a Spiral galaxy as shown in the illustration?
