Protons have a positive energy charge, while neutrons have a neutral charge
Answer:
I think it's the most important part in this
That's THERMAL energy, often referred to as "heat".
They almost entirely reside within galaxies because quasars are a subset of blackholes with a large and fast enough accretion disk to generate a beam of interstellar material perpendicular to itself. This typically only occurs in the largest black holes at the center of galaxies (supermassive blackholes) or at least stellar black holes---which still occur within galaxies because the material is necessary to form them.
